Good news! These Mobility35 projects were completed on time and on budget. We are committed to improving mobility and reducing congestion along I-35.
This project constructed three new flyovers at the I-35 and US 183 interchange and reconstructed the existing northbound I-35 to northbound US 183 flyover. The project also completed extensive work at St. Johns Avenue such as reconstructing the bridge and adding non-signalized U-turns and intersection bypass lanes in each direction. Other project improvements included extended entrance and exit ramps and enhanced bicycle and pedestrian accommodations throughout the corridor.
This project replaced the traditional intersection with a diverging diamond interchange (DDI). The project also reconstructed the northbound bypass lane, added a southbound bypass lane, constructed additional turn lanes at the intersection of Parmer Lane and North Lamar Boulevard and improved bicycle and pedestrian paths throughout the corridor.
This project replaced the existing Ronald Reagan Boulevard bridge with separate eastbound and westbound bridges. Both bridges now accommodate one travel lane, bike lane and six-foot sidewalk. The project also realigned eastbound Ronald Reagan Boulevard to tie into the new eastbound bridge.
This project converted the northbound and southbound I-35 frontage roads between Corn Hill and FM 972 from two-way to one-way traffic. In addition, nine entrance and exit ramps were built within the project limits.
The project reconstructed bridge structures and built new U-turns at the Stassney Lane and William Cannon Drive bridges. Additionally, the project reconstructed the frontage road bridges over Williamson Creek, widened the mainlanes, reconfigured entrance and exit ramps and improved bicycle and pedestrian accommodations throughout the corridor.
This project included replacing the existing interchange configuration with a new I-35 mainlane bridge over an at-grade reconstructed Posey Road. The project also added U-turn lanes in each direction and turn lanes at the northbound and southbound I-35 frontage road intersections, reversed six entrance and exit ramps between Centerpoint Road and York Creek Road, and enhanced pedestrian sidewalks and bicycle paths.
The project included reversing ramps along northbound I-35 between Grand Avenue Parkway and SH 45 North, constructing an extended entrance/exit lane along the northbound frontage road and installing high-mast lighting and improvements at Picadilly Drive.
The project included reconstructing and widening the northbound I-35 frontage road from two to three lanes, constructing a new extended entrance and exit lane on the northbound I-35 frontage road and relocating the RM 1431 exit (#256).
The project included the reconstruction of the Oltorf Street bridge, improved entrance/exit ramps and frontage roads, the construction of new extended entrance/exit lanes for mainlanes and ramps, and the addition of U-turns in both directions at Oltorf Street. Bicycle and pedestrian enhancements were also made along the I-35 frontage roads in each direction within the project limits.
The project replaced the CR 305 bridge over I-35 with a wider and taller bridge. Additionally, CR 304 East was realigned to connect to the newly constructed bridge which allows for better turning movements. Pedestrian enhancements were also made within the project limits.
The project included new braided ramps (where one ramp crosses over the other) that have been constructed along the northbound I-35 mainlanes between Hesters Crossing and RM 620 to eliminate merging conflicts. The north and southbound intersections of US 79 and I-35 frontage roads have also been reconstructed to add a third left-turn for westbound US 79. Northbound I-35 mainlane widening and bicycle and pedestrian enhancements were also part of this project.
Two ramps on the southbound I-35 frontage road between RM 1431 and FM 3406 were reconstructed and reversed to address traffic congestion and improve I-35 frontage road and mainlane operations. Bicycle and pedestrian safety enhancements have also been made.
The project included reconstructing the I-35 at FM 3406 bridge over I-35, I-35 frontage road improvements and FM 3406 intersection improvements. Bicycle and pedestrian enhancements have also been made.
The project included a new roundabout at the southbound I-35 frontage road and 51st Street intersection, a southbound intersection bypass lane underneath 51st Street, and reconfigured entrance and exit ramps. Bicycle and pedestrian enhancements, such as raised crosswalks and pedestrian safety beacons, have also been made.
One new ramp was added and five existing ramps were modified between RM 150 and the Blanco River.
Work included replacing the Slaughter Creek overpass with a new, wider bridge featuring one travel lane in each direction and a center-turn lane, adding a new southbound to northbound U-turn bridge, widening the southbound I-35 frontage road to two lanes through the intersection and installing safety lighting from Slaughter Lane to Onion Creek Parkway.
