Check out the latest Northwest Austin transportation updates, including ongoing projects along major highways and roadways.

183 North Mobility Project

Project: The project features two express lanes in each direction on US 183, a general-purpose lane to bring the number of nontolled lanes to four in each direction, new shared-use path connections, new sidewalks and cross-street connections for bicycles and pedestrians.

Update: According to the Central Texas Regional Mobility Authority, crews are working to complete concrete surface grinding and paving along the mainlanes, with lane closures beginning at 8 p.m. Work is expected to last throughout the summer.

Timeline: 2022-26
Cost: $612 million
Funding source: federal funding, sale of toll revenue bonds

Loop 360 at Courtyard Drive/RM 2222

Project: The project is part of the Texas Department of Transportation's slate of projects along 14 miles of Loop 360 in West Austin and is part of the Texas Clear Lanes congestion relief initiative. This segment will remove the traffic signal from the Loop 360 main lanes at Courtyard Drive and construct an overpass, reconfigure RM 2222 at Loop 360 to a diverging diamond interchange, and add shared-use paths and sidewalks.

Update: According to TxDOT officials, crews broke ground on the project April 29.

Timeline: 2026-29
Cost: $68.4 million
Funding source: Austin 2016 mobility bond, TxDOT

Spicewood Springs Road Regional Mobility Project

Project: The project includes widening the two-lane road into a four-lane road with left-turn bays, creating two water detention ponds and pedestrian and bicycle shared-use paths, and improving the storm drain system, water transmission and wastewater lines.

Update: According to city information, crews adjusted travel routes south of Adirondack Trail in March with signage and temporary lane markings to shift traffic to the western side of the right of way. The road currently remains in one lane in each direction from Adirondack Trail to the top of the hill.
