The formerly rural road—located along the southwest edge of Williamson County—has become one of the most traveled roads in Cedar Park, according to a March 5 news release from the city.
The project reconstructed the road from Whitestone Boulevard to just past Gaspar Bend. A partnership between the city of Cedar Park and Williamson County, the project began in January 2017 and was completed in early March.
A ribbon cutting commemorating the project's completion took place March 6.
“This has been a very important project to Cedar Park,” said Cynthia Long, Williamson County Precinct 2 commissioner, at the event. “It’s an exciting project especially for folks who travel it every day.”
The first phase included making both the north and south ends of the project four lanes. The middle section was expanded to two lanes, which will be expanded to four lanes in the future, according to the city of Cedar Park's news release.
The project also includes turn lanes at several driveways and intersections to better traffic flow, according to the statement. Lighting and sidewalks were part of the project as well.
Originally slated to be complete in spring 2018, the Anderson Mill Road project faced delays, including an extension due to a change in the project scope.
Sam Roberts, Cedar Park's assistant city manager, said construction phasing was a challenge due to constraints of the neighboring quarry and wildlife preserve. The project was bounded on the south end by the Balcones Canyonlands Preserve, an endangered species preserve, and much of the remainder of the road was constrained by Lime Creek Quarry, he said.
“It was a very narrow area to work in,” Roberts said.
Construction cost $7.3 million, which was paid for through voter-approved road bond funds from Williamson County and 2015 voter-approved street and road bond funding from the city of Cedar Park, according to the release.
Roberts said the city is preparing to begin Phase 2 of the project, which is also funded by the 2015 bond program. He said construction on the next phase will likely begin in 12-15 months.
