TxDOT to launch traffic study of Parmer Lane in Cedar Park

Daily traffic expected to double by 2035 in the high-growth corridor, officials say


The Texas Department of Transportation will be conducting a traffic study of Parmer Lane this month in Cedar Park, officials said. 

The study will be looking at a 4.4 mile corridor of Parmer Lane between RM 1431 and SH 45 N to determine potential roadway improvements, said TxDOT Spokesperson Diann Hodges.

“There has been significant growth in the corridor,” Hodges said. “The study will determine possible environmental impacts, conduct traffic modeling and complete public outreach.”

Eventually, the plans are to add an extra lane in both directions in that section, turning it into a six lane roadway.

As Cedar Park and Austin’s populations experience steady growth, city officials expect the Parmer Lane area of town to grow around the developing Presidio Station district. The mixed-use development will include 25,000 square feet of office space and 26,000 square feet of restaurant and retail, as well as hundreds of residential units said, Phil Brewer, director of economic development for Cedar Park. 

“It’s kind of the flavor du jour of the area, and will be a hot spot on Parmer,” he said. “That is our preferred campus site we’ve been marketing for a couple of years. There’s a tremendous amount of potential for it to develop into something cool.” 

In 2015, average daily traffic was 32,954. By 2035, the daily traffic is projected to double to 65,910, according to TxDOT traffic map data.

“Most of the growth in that area is residential and will continue in the future, based on what I’m seeing within our city limits,” Brewer said. “Once it gets developed, you’ll see some smaller retail types of businesses develop around it.”

The traffic study is expected to be complete by summer 2020, and will not impede traffic, Hodges said.

“(After public outreach is completed,) TxDOT evaluates each response from the public and determines the best path forward in the final design of the corridor,” she said. “This could include signal timing, additional left turns and additional right turns.”  

Following the study, the final design of the corridor will take place, followed by putting the project out to bid, and then construction. The study will cost $2.5 million, funded exclusively by TxDOT, Hodges said.
