6 ongoing transportation projects Northwest Austin residents should know for 2019

1

From a groundbreaking to design work, here are six projects that are making progress in 2019 in Northwest Austin or the Austin metro.

TxDOT makes progress on adding flyovers between I-35, US 183

The project involves adding three flyovers between I-35 and US 183, rebuilding the St. Johns Avenue bridge with new U-turns and a bypass lane, extending entrance and exit ramps, improving the existing northbound I-35 to northbound US 183 flyover, and improving bicycle and pedestrian facilities.

Timeline: January 2018-mid-2021
Cost: $124 million
Funding source: TxDOT

Agencies partner to add flyovers to Toll 290 and SH 130 interchange

The Central Texas Regional Mobility Authority and Texas Department of Transportation are funding the construction of three flyover connections between two toll roads: from eastbound Toll 290 to southbound SH 130, and from northbound and southbound SH 130 to westbound Toll 290. The project broke ground in December.

Timeline: December 2018-late 2021
Cost: $127 million
Funding sources: Mobility Authority, TxDOT

TxDOT proposes overpass at Spicewood Springs Road

The TxDOT project team is processing comments from the November open house meeting and will make any changes it can based on feedback.

Design of Anderson Mill Road improvements nears 60 percent completion

The city expects to host a public meeting in early 2019 on the 60 percent complete design plans.

Timeline: 2020-21 (construction)
Cost: $7.26 million
Funding sources: city bonds, funds

Planning could resume on US 183 North toll project

The Texas Transportation Commission—the governing board for TxDOT—is slated to approve a project-development agreement and adding the proposed toll road to the state highway system at its Jan. 31 meeting.

Four total toll lanes, two in each direction, will be added to US 183 between MoPac and RM 620. The Mobility Authority would handle construction of the new toll lanes as well as the fourth continuous nontolled lane that TxDOT is financing for $105 million. The existing three main lanes in each direction will remain nontolled as well as the new fourth lane.

Timeline: spring 2020-2024 (construction)
Cost: $450 million
Funding sources: Mobility Authority, TxDOT

Final design for corridor improvements will advance later in 2019

The city will start the final design phase in mid-2019 for improvements on Burnet Road and North Lamar Boulevard. Preliminary engineering will wrap up in early 2019, and City Council is expected to approve moving to final design in the spring.

Timeline: 2021-24 (construction)
Cost: $120 million
Funding source: 2016 Mobility Bond

    $250 million seems like a lot for the Loop 360 at Spicewood Springs project. Is there any information about what might make this project relatively expensive?
