The Mobility Authority also has two additional projects on US 183 that, combined, run from MoPac to north of Hwy. 29. The transportation agency provided updates on all three projects during a board meeting Aug. 25.
183 South in the final stages
With construction nearing completion, acting Mobility Authority Director of Engineering Mike Sexton said the remaining projects are “punch list items,” including roadway surfacing and final striping.
“You'll continue to see some night closures out there as they do these items, but the project's essentially open to traffic, and you won't see impacts during the day,” Sexton said.
It has up to three lanes in each direction and also invested $25 million in bicycle and pedestrian facilities, according to the Mobility Authority website. The project yielded 7 miles of sidewalks, 16 miles of bike paths and 10 miles of shared-use paths.
The 8-mile stretch of toll road runs from Hwy. 290 to Hwy. 71.
183A Toll Phase 3 making steady progress
Phase 3 of the 183A Toll project broke ground in April and is 13.6% of the way to completion. The work thus far has included preparing the right of way, building substructures for bridges and utilities work.
“If you drove in the corridor, they are blowing and going out there. They have torn it up, which is good,” Sexton said. “We want them out there working. Get it done early if we can.”
According to the Mobility Authority, the toll road spans 11 miles from RM 620 through Cedar Park and Leander. The project’s third phase is a 5.3-mile stretch that extends northward from Hero Way to north of Hwy. 29, with a total cost of $277 million. It is on track to be open to tolling by early 2025.
183 North Mobility Project 30% design ready this fall
The project will add a 9-mile express lane along US 183. Construction is expected to begin in the fourth quarter of 2021.
“We're having weekly meetings that last all day, working through their design packages,” Sexton said. “Their 30% should be coming in the month of September.”
The stretch of toll road runs from SH 45 N to MoPac. The project has an estimated cost of $612 million, according to the Mobility Authority website.
