US 183 begins concurrent with
US 77 Alt at its southern terminus one block north of downtown
Refugio at an intersection with
US 77; the two highways subsequently travel north through mostly rural farmlands across the
Gulf Coastal Plains. After serving the
Presidio La Bahía, US 183 crosses the
San Antonio River to serve the
Goliad State Park and Historic Site and the city of
Goliad, intersecting
US 59 in the center of town. Traveling through additional farmlands and forests, US 183 eventually forms a concurrency with
US 87 just before crossing the
Guadalupe River and travels along Espalande Street through downtown
Cuero, ending its concurrency of US 87 in the town center. North of Cuero, US 77 Alt splits off to the northeast, while US 183 continues parallel to the Guadalupe River's course. The highway cuts through the historic
Battle of Gonzales site and borders the city of
Gonzales to the west, intersecting
US 90 Alt to the northwest of the city. Running parallel to the
San Marcos River, US 183 provides access to
Palmetto State Park before crossing
I-10 and forming a concurrency with
US 90 west to
Luling via Pierce Street. In the center of Luling, US 183 leaves US 90 and turns onto Magnolia Avenue, traveling due north past many decorated
oil wells. Continuing through rural farmlands, US 183 eventually enters
Lockhart, being the main north-south route through the city. The highway then merges onto the
SH 130 frontage roads just north of Lockhart, following them until
Mustang Ridge where SH 130 splits northeast to follow
SH 45 and US 183 continues north into
Colton and
Pilot Knob. As US 183 crosses into
Austin and intersects several local roads providing access to
McKinney Falls State Park, it borders the west side of
Austin-Bergstrom International Airport before having an interchange with
SH 71 and enters Austin's Montopolis district. US 183 crosses the
Colorado River adjacent to the old
Montopolis truss bridge prior to serving a major fork east of the Govalle district, making a
sigmoid curve east to serve the Colony Park district. US 183 eventually becomes a six-lane freeway north of the Windsor Park district just before crossing
US 290, curving west to serve
I-35 and
Loop 275 (Lamar Boulevard); north of Lamar Boulevard, the US 183 frontage road is redesignated as Research Boulevard throughout the rest of its length in Austin. The highway makes another sigmoid curve to the north before an interchange with
Loop 1 (Mopac Expressway). After an interchange with
Loop 360 (Capital of Texas Highway), US 183 serves much of northwest Austin. It eventually intersects
SH 45 near
Lakeline Mall and becomes a surface street while the freeway continues on the east side as
183A Toll Road. US 183 continues as Bell Boulevard through west
Cedar Park before intersecting 183A in
Leander. Continuing north, US 183 runs mostly through forests and farmland as it crosses the North and South Forks of the
San Gabriel River. After turning through several hills east of the
Texas Hill Country, US 183 bounds northwest into
Lampasas, where it runs on Key Avenue concurrent with
US 190 and
US 281 through fourteen blocks in the city's downtown and recreational areas before splitting to the northwest from US 281 north of Lampasas. US 183 and US 190 continue traveling northwest through rolling hills, eventually splitting southeast of the
Lometa city limits. US 183 continues to run parallel to the Colorado River before beginning a concurrency with
US 84 north of the
Goldthwaite city limits. The two highways continue northwest for a long distance before reaching
Early and joining
US 67 and
US 377 at the town's center. The four highways travel west for roughly eleven blocks before US 183 splits to the north and serves
Brownwood Regional Airport. US 183 continues due north, crossing
SH 36 in
Rising Star and later
I-20 just south of
Cisco. South of
Throckmorton,
US 283 joins the highway, an overlap that lasts until
Vernon, where 183 joins
US 70 and
US 287. In
Oklaunion, US 70 and 183 leave US 287 and cross the
Red River together into Oklahoma. ==History==
