1. New RR 620 lane

A new auxiliary southbound lane on RR 620—from just north of Lohmans Crossing to Spillman Loop in Lakeway—will be added this summer. The project also includes adding pavement at several RR 620 intersections including Falcon Head Boulevard and Ladera Boulevard to allow a three-lane approach on the west side of the intersections. This configuration will match the east side of these intersections. Timeline: May-August Cost: $1.42 million Funding sources: Texas Department of Transportation

2. Cold Water Lane segment closure

A section of Cold Water Lane near its intersection with 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.

Timeline: March 21-early June Cost: $813,000 estimated Funding sources: city of Lakeway

3. Loop 360 entrance/exit lanes

The TxDOT 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.

Timeline: February 2016-spring 2017 Cost: $6.44 million Funding sources: TxDOT

4.5. RR 620 intersections

The 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

6. Hwy. 71 Improvement Project

Construction on Phase 4 began in mid-October for the area from Silvermine Drive to just south of Scenic Brook Drive. That work, which is still underway, involves adding shoulders and a continuous center turn lane and is anticipated to be completed by summer 2016. When the overall project is complete, parts of the project area will consist of five lanes, including a dedicated center left-turn lane, shoulders, a new pavement surface and striping.

Timeline: summer 2014-summer 2016 Cost: $15.9 million Funding sources: TxDOT

7. 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

8. 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.

Road paving on Flint Rock began in January and forced the May 9 temporary closure of Wild Cherry Road. Officials anticipate reopening Wild Cherry in late 2016. Wild Cherry traffic has been rerouted onto new portions of Flint Rock.

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
