Citizens, TxDOT discuss RM 2243 study


About 120 residents attended a TxDOT open house on Nov. 29 at Dell Pickett Elementary School to discuss a corridor study on RM 2243 between 183A and I-35 in Williamson County. 

Already one of the fastest growing counties in Texas, the Williamson County population is expected to increase by another 80 percent between 2017 and 2040. In order to keep up with the accelerated growth and subsequent traffic, Williamson County has identified RM 2243 as a potential future controlled access roadway in its current Long-Range Transportation Plan. 

The study is a part of determining future roadway improvements to address traffic growth and connectivity to 183A and I-35.

“We’ve been asked to study the 2243 Corridor to see what improvements can be made there,” said TxDOT Communications Director Diann Hodges. “We’ve had a really great opportunity to connect Leander and Georgetown as a way to get across east to west along the larger Austin district. We don’t have a lot of opportunities with a lot of traffic in those directions. Ultimately, this could be a very large thoroughfare that could move a lot of traffic so this is an opportunity for people who live in the area to take a look, see what we’re proposing and see how it affects them.”

Potential improvements include widening the mainlanes between 183A and Southwest Bypass to three travel lanes in each direction with the outside lanes operating as auxiliary lanes, constructing frontage roads with three travel lanes in each direction and providing a new connection to US 183A.

“If you look at east-west corridors throughout Williamson County, you’ve got 45, 25, 195, there’s really not anything in between so that why we’re looking at another east-west corridor,” said TxDOT Assistant Area Engineer John Peters. “We want to listen to our members of the community and build the best project for them and for the state of Texas.”

Between Southwest Bypass and I-35, the proposed roadway would include a four-lane divided road with two travel lanes in each direction. East and westbound traffic would be separated by a median and turn lanes would be provided at various locations. The potential improvements would require a typical right-of-way width of approximately 350 feet and approximately 500 feet at intersections. 

TxDOT is gathering input from the public on what concerns may exist to help identify the best option or options that could be further studied in future project development phases. For the RM 2243 corridor study, TxDOT has examined various traffic projections in order to estimate future roadway needs. Because of the long-term examination for the corridor study, this is a planning level study and does not include the development of construction plans.

Any future proposed project or projects resulting from the corridor study will require funding, additional engineering design, environmental studies and public involvement opportunities before construction may begin.
