The letter will be sent to the Central Texas Regional Mobility Authority with a list of conditions required in order for the project to be supported by the two cities, including funding a diverging diamond intersection off MoPac and Bee Cave Road, implementing traffic noise barriers on the Rollingwood side of the highway and maintaining lane elevation at the designated height.
According to West Lake Hills Mayor James Vaughan, the diverging diamond intersection will reduce peak-hour delays by 48%-58%, with eastbound delays reduced by 33%-50%, westbound delays reduced by 57%-83% and northbound delays reduced by 75%.
Currently, the MoPac South project lists the intersection as “pending funding coordination with local municipalities," yet in order for West Lake Hills and Rollingwood to support the assessment, the diverging diamond must be fully funded.
“There will not be funding for a $10 million intersection from the city of West Lake Hills,” Vaughan said.
