US 35 is signed north–south in West Virginia and Indiana, while in Ohio it is signed east–west.
West Virginia As of November 11, 2021, the final
West Virginia portion of the highway has been expanded to four lanes, mostly along a completely new route. In
Putnam County, the roadway that becomes US 35 is a short, four-lane,
divided, unsigned
US 35 Spur running northward from Teays Valley Road toward
I-64 on the edge of
Scott Depot in
Teays Valley. Remaining on the edge of Scott Depot, and now at the edge of Teays Valley, the roadway reaches US 35's southern terminus at its junction with I-64, where the route becomes an expressway. US 35's junction with I-64 is a hybrid
semi-directional T/
diamond interchange. All movements between US 35 and I-64 are
free-flowing, except for eastbound I-64 to northbound US 35. The interchange also handles movements between I-64 and the US 35 spur similar to a diamond interchange. Proceeding north from I-64, US 35 has two intersections, followed by an interchange with
West Virginia Route 34 (WV 34). There follow a number of intersections along the route, with one being an indirect connection to
WV 817, the former path of US 35. The next major junction is
WV 869, which travels across the
Kanawha River on the Lower Buffalo Bridge (often referred to as the "Buffalo Bridge"), connecting via
WV 62 to the town of
Buffalo and the nearby, large
Toyota engine and transmission plant. The route continues as an expressway. At
WV 2, which leads to
Point Pleasant, there is a
partial cloverleaf interchange with six ramps; all movements are free-flowing except for northbound US 35 to southbound WV 2, and from southbound WV 2 to southbound US 35; the interchange is partially in
Henderson. At this point, US 35 becomes a
freeway and remains so, as it immediately crosses the
Ohio River on the
Silver Memorial Bridge, and enters Ohio.
Ohio US 35 is signed east–west in Ohio, an exception to the
numbering scheme for US Highways, which calls for odd-numbered routes to be signed north–south, as is US 35 in West Virginia and Indiana. Continuing as a
freeway, US 35 crosses the
Ohio River from West Virginia on the
Silver Memorial Bridge, and enters
Gallia County, Ohio. The first, partial interchange, providing a westbound exit and an eastbound entrance, is with
State Route 7 (SR 7), just outside the village of
Gallipolis. Just after that, still, outside the village, the highway passes adjacent to the
Gallia–Meigs Regional Airport within Gallipolis; there is another partial interchange, providing an eastbound left exit and a westbound left entrance to
SR 735, which connects to SR 7. From there, US 35 continues west, where there is a
hybrid interchange with an unusual configuration at
SR 160. SR 160 roughly parallels US 35 to the south; there is a westbound exit to SR 160 north which uses a
flyunder ramp, an eastbound entrance from SR 160 south, and an eastbound entrance from SR 160 north. Additionally, another fly under ramp from SR 160 north merges with the westbound exit ramp; that exit ramp, in turn, splits to form an entrance ramp to westbound US 35. This interchange lacks an eastbound exit. As SR 160 turns north, it diverges from US 35, which travels somewhat northwest. There, US 35 once again meets SR 160, this time at a partial interchange with an eastbound exit and a westbound loop ramp entrance. Turning more west-northwest, there is an interchange at
SR 850 (Rodney Pike), followed by a
rest area in each
direction. Approaching the edge of
Rio Grande, the route turns west and then west-southwest, where there is an interchange at
SR 325. Past the village, the highway travels northwest and becomes a four-lane, at-grade
expressway when it reaches the
Gallia County village of
Centerville; here there is an intersection with
SR 279 west. Traveling north-northwest and northwest into
Jackson County, the expressway configuration continues until
SR 327, where there is a
grade-separated,
one-quadrant interchange, with the connecting road in the southeast quadrant of the junction. The road resumes as an at-grade expressway, approaching and then skirting the edge of
Jackson. The route then reaches a grade-separated,
right-in/right-out interchange; westbound there is a right-in/right-out at Keystone Furnace Road; eastbound there is a right-in/right-out at McCarty Lane; these roads are connected via Industry Drive and Acy Avenue, which
overpasses US 35. Next, there is an unusual interchange configuration at
SR 32/
SR 124, which is an expressway in both directions. Each highway has ramps that exit to the other highway, with traffic merging onto the second highway, but traffic coming to an intersection. Both highways end up having intersections, albeit with grade separation of the main highway corridors. This interchange type is sometimes termed a
"windmill" interchange, but it is not related to the interchange type of the
same name. This junction is the only interchange of its type known to exist in the world. Soon after passing the last interchange and still skirting Jackson, the highway once again becomes a freeway and has an interchange at Pattonsville Road/Broadway Street. Turning briefly north, then northwest, the route leaves Jackson and reaches an interchange with
SR 93. It next has an interchange with
Jackson County Road 84 (Chillicothe Pike). After the last interchange, the highway becomes an at-grade expressway for about . Along this section, there is a rest area next to the westbound
lanes but accessible from both directions, with additional access via Cain Road (
Jackson Township Road 213). US 35 then turns roughly west, entering
Ross County and reaching an interchange with Vigo Road/Watson Road at
Richmond Dale. At this point the route again becomes a freeway. Turning north and northwest, the section between Richmond Dale and
Chillicothe includes a large cut through a ridge and provides westbound motorists with a panoramic view of the
Scioto River valley. Southeast of Chillicothe, westbound
US 50 joins US 35 in a concurrency at a
hybrid interchange; similar to a
diamond interchange, the exit ramp from US 35 east carrying US 50 east becomes a two-way road, curves around and crosses over US 35 about east; the other ramps connect to this
overpass. Next, US 50 west leaves the concurrency at a partial interchange at Eastern Avenue; there is only a westbound exit and an eastbound entrance. Then, the
US 23 north freeway joins US 35 in a concurrency at a
partial-Y interchange; there is an eastbound exit and a westbound left entrance. Turning north-northwest, US 35 skirts Chillicothe to the east, coming to an interchange at Main Street. Turning northwest, the
US 23 north freeway leaves the concurrency at a partial-Y interchange; there is a westbound exit and an eastbound left entrance. Turning west and skirting through city boundaries, there is a
partial cloverleaf interchange with five ramps at
SR 159 (Bridge Street); there is a loop ramp from northbound Bridge Street and a directional ramp from southbound Bridge Street to westbound US 35. Travelers eastbound near this interchange can see the hills that are shown on the
Great Seal of the State of Ohio. Turning northwest, just outside the city limits, there is an interchange at
SR 104 (High Street). The next, partial interchange, is at Pleasant Valley Road/Egypt Pike with a westbound exit and an eastbound entrance (via Larrick Lane). Continuing along, there is an interchange at
Ross County Road 550/
Pleasant Valley; despite this junction being a regular
service interchange, it is configured as a hybrid
trumpet interchange. Next is an interchange at Ross County Road 87, near
Frankfort. Continuing, there is an interchange at
SR 138. Entering
Fayette County, the road turns west-northwest, bypassing south of
Washington Court House. The next major junction is with
I-71 near
Jeffersonville; rather than have a direct interchange, each freeway indirectly connects to the other via interchanges with
SR 435. As the route continues through flat farmlands, it enters
Greene County, bypasses north of
Jamestown and south of
Xenia. At the junction for Exit 48 in Xenia, the left lane bypasses Xenia and the right lane becomes Business Route 35 East (running concurrently with Xenia's Main Street). Business Route 35 continues east until it meets US 35 at Exit 55. Between US 68 and US 42, the route is designated the "Sheriff Gene Fischer Memorial Highway" in honor of late Greene County sheriff Gene Fischer, who died unexpectedly on November 16, 2021. Past the Xenia bypass, the road reverts to an at-grade expressway. From a bit east of Orchard Lane in
Beavercreek Township to a bit west of Factory Road in
Beavercreek, the route has a
superstreet configuration. US 35 once again returns to freeway status at the North Fairfield Road interchange in
Beavercreek. It next has a full-access interchange with
I-675, also in Beavercreek. in
Dayton, Ohio Several miles later, in
Montgomery County, the road opens into a three-lane highway (with five lanes in some parts) each way through downtown
Dayton. Turning west, the highway has a full-access interchange with
I-75 in downtown Dayton. Past I-75, the route becomes an expressway, with a mix of interchanges and at-grade intersections. After entering
Drexel, just west of Dayton, the highway turns north. At the border with
Trotwood, the route turns due west on West Third Street/Eaton Pike; the roadway that had carried US 35 continues as
SR 49, an at-grade expressway also known as the "Northwest Connector" or as the "Trotwood Connector". The roadway carrying US 35, now two lanes and undivided, travels through
New Lebanon as Main Street. US 35 then enters
Preble County and travels through
West Alexandria as Dayton Street. The route next proceeds to
Eaton; after passing through downtown as Main Street, the route turns northwest onto Eaton Richmond Pike (Main Street continues as
SR 122). The highway travels toward
I-70 near
New Paris, widens to four lanes as it approaches
SR 320, turns north and briefly becomes four lanes undivided, then reduces to single-lane ramps and merges with the Interstate at a partial interchange. Running concurrently with I-70, US 35 travels approximately to the Indiana state line.
Indiana US 35 enters
Wayne County, Indiana concurrent with
I-70 and passes north of
Richmond, before splitting off on the northwest side of Richmond. US 35 then travels in a northwesterly path as a winding two-lane highway, passing through agricultural land, and through intersections with
State Road 38 (SR 38),
SR 1 and, in
Randolph County,
US 36. The highway then passes through a corner of
Henry County, with no major junctions. In
Delaware County, the highway reaches the edge of the city of
Muncie, where it merges with
SR 3 and
SR 67 as a four-lane expressway. The expressway heads north, skirting the east side of Muncie, passing over the
White River and through interchanges with Memorial Drive in
unincorporated Center Township and
SR 32 in Muncie. Continuing along the east edge of Muncie, there is a
right-in/right-out intersection in both directions with East Centennial Avenue and an intersection with East McGalliard Road. Northeast of Muncie, at the border of unincorporated Center Township and
Hamilton Township, there is an intersection with East Riggin Road. Shortly thereafter, SR 67 splits off the expressway at an interchange, followed by a partial interchange with Old State Road 3, leading back into Muncie. Soon after the expressway ends, with the roadway becoming a two-lane highway. Near the town of
Royerton, US 35 turns west onto
SR 28, toward
I-69, as SR 3 continues north. After a short overlap with SR 28, US 35 turns north onto I-69. US 35 overlaps I-69, passing into
Grant County, through an interchange with
SR 26, to
SR 22, where US 35 leaves I-69 and heads west on SR 22 to travel through the cities of
Gas City and, in
Howard County,
Greentown. Just east of
Kokomo, US 35 turns north onto the
US 31 freeway. It overlaps US 31 for only , to a partial interchange where it splits off, heading west as a two-lane roadway. US 35 passes just north of a
Chrysler manufacturing plant before an intersection with
SR 931, the former route of US 31. The roadway briefly widens to a four-lane divided highway at a partial interchange with Davis Road, which connects from Kokomo. US 35 leaves the Kokomo area heading northwest into
Cass County, toward
Logansport. As US 35 nears Logansport, the roadway becomes a four-lane expressway, just prior to its intersection with
US 24. The expressway bypasses Logansport to the south as part of the Hoosier Heartland Highway. There is a northbound (westbound) exit to Monticello Road, the former routing of these highways. Northbound US 35 and westbound US 24 exit the Hoosier Heartland Highway at a
split diamond interchange and run concurrently along the interchange's westbound
frontage road, having a very short overlap with
SR 25 (southbound US 35 and eastbound US 24 run concurrently along the eastbound frontage road, also overlapping SR 25). US 35 and US 24 then turn northwest from the frontage road onto another expressway on the west edge of Logansport. Along the roadway, there is an intersection with the aforementioned Monticello Road and a
two-quadrant interchange with Old State Road 25. After crossing the
Wabash River, the overlapped routes have a final interchange where US 24 exits heading due west, while US 35 continues north-northwest. Soon after US 24 leaves US 35, US 35 narrows back to a two-lane road and travels through the town of
Winamac, in
Pulaski County. Once in
Starke County, the route travels through the town of
Knox. In
Davis Township, near
Hamlet, the
US 30 expressway provides an interchange. After entering
LaPorte County, US 35 travels to the community of
South Center in
Union Township; there it turns west on
US 6 (the US 35 roadway continues north as South
County Road 300 E). The route next turns north-northwest until it leaves the concurrency with US 6 northward in
Washington Township, near
Kingsbury. Turning northwest, US 35 travels through the city of
La Porte; in northwestern La Porte, an intersection with
SR 39 provides access to the
Indiana Toll Road/
I-80/
I-90. US 35 next crosses under the Indiana Toll Road with no direct interchange access, in unincorporated
Center Township. Farther northwest, US 35 has its northern terminus where it meets
US 20 in
Springfield Township, just east of an interchange with
I-94, near
Michigan City.
Logansport issues Logansport area residents, the sheriff's department and at least one transportation expert have voiced concerns about the split diamond interchange used on the Logansport section of the Hoosier Heartland Highway. From the interchange's opening in October 2013 through February 28, 2016, there had been 71 two-vehicle crashes at or near the interchange, 53 of those at the interchange's four intersections, two fatalities, and a number of injuries. Possible causes for the accidents include drivers' unfamiliarity with this type of interchange, which is typically built in cities, and is not common in semi-rural small towns; drivers' mistaking the frontage roads for entrance ramps and not stopping when required; the complexity of four major traffic routes converging on one interchange; ramp/frontage traffic controlled by stop signs alone, with cross-traffic not having to stop; stop signs not clearly visible at the crest of the exit ramps. In response in 2014, the
Indiana Department of Transportation (INDOT) added signage, placed flashing lights on the stop signs, and installed rumble strips. These steps reduced, but did not eliminate the problems, with one of the fatalities taking place after these fixes. INDOT was planning by spring 2016 to add overhead flashers, move the stop signs to more visible positions, install channelizing islands and increase overhead intersection lighting. ==History==
