1. Cold Water Lane segment closure

A section of Cold Water Lane near Top O the Lake Drive in the city of Lakeway is temporarily closed to allow storm sewer culvert work on nearby streets. Additionally, a section of Top O The Lake at the intersection is reduced to one lane, and detour signage and barricades were placed in the area March 14. Construction on the culverts began March 21 by contractor Austin Underground.

2. Loop 360 entrance/exit lanes

The Texas Department of Transportation will add extended entrance and exit 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 in Austin. A left-turn lane will also be added on the northbound frontage road of MoPac at Loop 360.

3.4. RR 620 intersections

TxDOT will add a traffic signal on RR 620 at Dave Drive and a traffic signal at Oak Grove Boulevard in northern Lakeway before the 2016-17 school year begins in the fall, said Kelli Reyna, TxDOT Austin District public information officer.

She said the agency routinely studies major intersections to see if signals would be beneficial and determined that the intersections warrant a traffic signal.

Timeline: unknown-fall 2016 Cost: $150,000 for each traffic signal totaling $300,000 Funding sources: TxDOT

5. Spur 191 bridge open

The Spur 191 bridge at Cypress Creek in Spicewood opened April 1. The new 46-foot-long, two-lane bridge replaces a narrow, two-lane bridge and includes 7-foot shoulders on both sides as well as a 6-foot pedestrian sidewalk.

The improvement was needed for the safety and mobility of area drivers.

A Greater Austin Development Concrete Construction was the contractor for the project.

6. 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

7. 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 with a buffer and asphalt shoulder 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 in the fall 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.

Road paving of the project began in January and is expected to continue sporadically throughout the project until late 2016.

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
