3. Loop 360 auxiliary lanes

TxDOT will add auxiliary lanes, or extended turn lanes, on Loop 360 to improve intersections with Walsh Tarlton Lane, the Barton Creek Square Mall entrance, MoPac and the intersection just south of MoPac. A left-turn lane will also be added on the northbound frontage road of MoPac at Loop 360.

Timeline: winter 2015-spring 2017 Cost: $6.44 million Funding sources: TxDOT

4. MoPac toll lanes

Upon completion the highway will have one new lane in each direction from Parmer Lane to Cesar Chavez Street that will be tolled. Current construction includes bridge widening, building sound walls, installing conduit and cables to support the toll-collection and intelligent transportation systems, and completing the relocation of temporary ramps. The timeline was delayed from a fall 2015 completion to late 2016.

Timeline: late 2013-late 2016 Cost: $204 million Funding sources: federal and state funds

5. Bicycle/pedestrian bridge along MoPac over Barton Creek Greenbelt

Partnering with the city of Austin, TxDOT is constructing a bridge and shared-use path along northbound MoPac lanes over the Barton Creek Greenbelt from one frontage road turnaround to the other near MoPac’s intersections with Southwest Parkway and Loop 360. Remaining work includes adding columns, beams, railings and lights.

6. Flint Rock Road

Approximately 2 miles of the two-lane Flint Rock Road—between RR 620 at Lakeway Regional Medical Center and Serene Hills Drive—will be widened, and an asphalt shoulder will be added. The project is expected to take 15 months to complete depending on the weather, and Travis County will manage the construction phase performed by Smith Contracting Co. Construction began the week of Oct. 19 with the erection of signage and erosion protection. Early segments of the project include brush clearing and the construction of temporary travel lanes for traffic control.

Timeline: October 2015-late 2016 Cost: $9.2 million total with 47 percent funded by the city of Lakeway and 53 percent funded by Travis County Funding sources: city of Lakeway, Travis County
