AUSTIN (KXAN) — On Monday, the Capital Area Metropolitan Planning Organization’s (CAMPO) transportation policy board voted to approve a $225,000 interchange bottleneck study with engineering firm HDR.

The study will address areas where major roads meet but lack connections, including interchanges along Interstate 35, State Highway 130, State Highway 71 and MoPac Expressway.

“We’re looking at major corridors in the region that are not already undergoing some kind of implementation or don’t have a specific plan in place for future improvements,” explained Doise Miers, the community outreach manager for CAMPO.

CAMPO’s Bottleneck Study Area features 11 locations across Central Texas.

CAMPO points to the interchange at I-35 and U.S. Highway 183 as an example of a connected area. These drivers have the option to travel in various directions using flyovers.

For areas where connections do not exist, drivers have to search for frontage road connections or other nearby highway crossings to get to where they’re going. CAMPO reports that could cause longer commute times and add to traffic congestion.

“The region is so quickly growing and transportation projects can be expensive, and they can take quite a bit of time,” Miers said, “so how can we maximize what’s already on the ground today and make that system work as efficiently as possible?”

Some solutions for repurposing a road include a diverging diamond intersection or DDI. That’s where traffic travels on the opposite side of the road to bypass the intersection. Miers said other options could be constructing flyovers.

The approved study will take approximately two years to complete. Following its completion, CAMPO will meet with area transportation partners like the Texas Department of Transportation to review its findings.
