Oregon The western terminus of US 30 is at an intersection with
US 101 at the southern end of the
Astoria–Megler Bridge in downtown
Astoria,
Oregon, approximately from the
Pacific Ocean. It heads east to
Portland, where it uses a short section of
freeway built for the canceled
I-505. From there, it heads around the north side of downtown on
I-405 and
I-5 to reach
I-84. Most of the rest of the route is
concurrent with I‑84, with only about , under a fifth of its remaining length, off the freeway, mainly on old alignments.
Idaho Upon entering
Idaho, US 30 runs along its old surface route through
Fruitland and
New Plymouth before joining I‑84. It leaves at
Bliss and soon crosses the
Snake River, running south of it through
Twin Falls and
Burley before crossing it again and rejoining I‑84. At the split with
I-86, US 30 continues east with I‑86 almost to its end at
Pocatello. US 30 cuts southeast through downtown Pocatello to
I-15, where it heads south to
McCammon. There, it exits and heads east and southeast into
Wyoming, not paralleling an
Interstate Highway for the first time since Portland.
Wyoming In
Wyoming, US 30 heads southeast through
Kemmerer to
Granger, where it joins
I-80 across the southern part of the state. It is also here that it joins the historic
Lincoln Highway. As in the previous two states, US 30 remains with the Interstate Highway for most of its path, only leaving for the old route in the following places: • from
Walcott to
Laramie • through
Cheyenne • through
Pine Bluffs to the
Nebraska state line
Nebraska Unlike the three states to the west,
Nebraska keeps US 30 completely separate from its parallel Interstates (
I-80 in this case). From the state line to
Grand Island, US 30 closely parallels I‑80. East of Grand Island, US 30 diverges from I‑80 and runs northeast toward
Columbus on a highway parallel to the
Platte River. At Columbus, it turns east toward
Schuyler and
Fremont and crosses the
Missouri River into
Iowa east of
Blair.
Iowa US 30 crosses Iowa from west to east approximately north of
I-80. Between
Missouri Valley and
Denison, US 30 runs in a southwest–northeast direction. The majority of US 30 east of
Ames and west of the
Mount Vernon–
Cedar Rapids area () is a rural four-lane divided highway. A portion of the highway in
Tama County is being upgraded to a divided highway. US 30 between Mount Vernon and
Dewitt is a two–lane highway. It crosses the
Mississippi River into
Illinois on the
Gateway Bridge at
Clinton. US 30S and US 30A are two previous alternate alignments of US 30 in Iowa. They followed the original alignment of US 30 in the state. They both began in Nebraska, entered Iowa in
Council Bluffs, and extended north to Missouri Valley via
Crescent to meet the current highway.
Illinois US 30 heads east in
Illinois to
Rock Falls, where it begins to parallel
I-88. At
Aurora, it turns southeast to
Joliet, where it is a major thoroughfare in the city of Joliet (Plainfield Road), and then back east through
New Lenox,
Frankfort,
Mokena,
Matteson,
Olympia Fields,
Park Forest,
Chicago Heights,
Ford Heights, and
Lynwood to the
Indiana state line, bypassing
Chicago to the south. Notwithstanding, the original 1926 routing of US 30 ran directly through downtown Chicago.
Indiana US 30 in
Indiana is a major rural
divided highway. It is not a freeway except at
Fort Wayne, where it runs around the north side on
I-69 and
I-469. Between
I-65 (at
Merrillville) and I‑69 (at Fort Wayne), there are over 40 traffic signals on this divided highway, hindering smooth traffic flow. This is especially pronounced near
Warsaw and
Columbia City, where the speed limit is reduced as the highway runs through a commercial section with many businesses and traffic signals. Many of the other signals are concentrated between
Hobart and
Valparaiso, the two cities being about apart. It is, however, a four-lane divided road through its entirety within Indiana, generally avoiding small towns. Speed limits range but are generally .
Ohio US 30 continues into
Ohio, where it is mainly a four-lane divided highway until
Canton. A proposal to make US 30 a limited-access freeway from Trump Avenue and
State Route 11 (SR 11) was set in 2019 and federal funding set $18 million (equivalent to $ in ) to construct the new freeway. , the only sections that were limited access freeways are in
Van Wert,
Bucyrus,
Mansfield,
Wooster, and Canton. A section between I-71 and US 250 is a divided four-lane highway. A section between
SR 57 and
SR 172 is a four-lane divided highway, with traffic signals at two intersections. The highway passes through Van Wert. After Van Wert, it travels through
Upper Sandusky where the highway runs concurrently with
US 23. The section between Mansfield and Canton follows the old Lincoln Highway. The last remaining segments that will be upgraded to a freeway are past Canton; currently, the highway is a two-lane route that passes through
East Canton,
Minerva, and
Lisbon. After Lisbon, it runs concurrently with
SR 45 for and becomes a freeway. Designated with signs marking routes SR 11,
SR 7,
SR 39, and US 30. After joining SR 11, SR 7 becomes a part of the freeway where all three routes split in
East Liverpool where US 30 joins SR 39 for and US 30 crosses the
Ohio River into West Virginia.
West Virginia US 30 runs for only about in
West Virginia. It crosses the
Ohio River over the
Jennings Randolph Bridge, continuing the freeway from the Ohio section. After cutting through the town of
Chester with only one interchange,
West Virginia Route 2 (Carolina Avenue), the freeway section ends not too long after. US 30 continues across the northernmost piece of the
Northern Panhandle on a two-lane road.
Pennsylvania , along the
Philadelphia Main Line, October 2018 US 30 heads southeast into
Pennsylvania, joining
US 22 and then the
Penn-Lincoln Parkway West west of
Pittsburgh. It heads through downtown Pittsburgh on
I-376/US 22, leaving at
Wilkinsburg for its own alignment. From there, it roughly parallels the
Pennsylvania Turnpike (
I-76) to the
Philadelphia area, though, in many areas, particularly from
York past
Lancaster, and bypassing
Coatesville,
Downingtown, and
Exton, it is far enough from the Pennsylvania Turnpike to require its own freeway. In Somerset County it mainly follows the old route of the
Forbes Road. As it approaches Philadelphia, US 30 constitutes the main road of the
Philadelphia Main Line, a string of affluent suburbs west of the city; often called Lancaster Avenue and Lancaster Pike through this stretch. US 30 then briefly joins I‑76 near
Center City, Philadelphia, splitting onto
I-676 as it crosses the
Delaware River on the
Benjamin Franklin Bridge.
New Jersey US 30 splits from
I-676 just east of the Benjamin Franklin Bridge toll plaza in
Camden and heads southeast to
Atlantic City, generally parallel to the
Atlantic City Expressway, passing through the
New Jersey Pine Barrens. For most of its New Jersey run, it is known as the White Horse Pike. It ends in Atlantic City at the intersection of Absecon Boulevard, Virginia Avenue, and Adriatic Avenue, about from the
Atlantic Ocean. ==History==
