Transportation updates for Northwest Austin heading into June


Ongoing Updates

MoPac construction

Work on the MoPac express lane project finished in March. The project added one managed-toll lane between Parmer Lane and Cesar Chavez Street, which is variably priced. The final completion does not include a separate approximately $4.5 million project that McCarthy Building Co. is finishing, which includes work on the sound walls by the intersection of MoPac and 45th Street. That work is scheduled to finish by July.

Timeline: October 2013-July 2019

Cost: $230 million

Funding sources: various local sources

I-35 Projects

Work continues with crews having finished six columns for the bridge beams on the northwest corner of I-35 and US 183. Texas Department of Transportation crews in April reduced the US 183 northbound frontage road from three lanes to two between US 290 to south of US 183. Drivers must take a new, temporary entrance ramp from the I-35 northbound frontage road north of US 290 to the I-35 northbound main lanes.

Crews are scheduled to demolish and rebuild the St. Johns Avenue bridge over the I-35 main lanes beginning in June. During the long-term closure, all vehicles on St. Johns will turn right onto the I-35 frontage roads and access either the US 183 or US 290 U-turn to access St. Johns on the other side of I-35. The new bridge is scheduled to open in the fall.

City officials expect construction to wrap before the end of June.
