After over three years of construction, the project is expected to wrap up this spring, according to TxDOT Communications Manager Brad Wheelis.
What's next
The remaining steps of the project include construction crews continuing to install lighting, place drainage systems and create shared-use paths along the frontage roads and Williams Drive.
Additionally, the Williams Drive bridge will be painted, which will require temporary lane closures, Wheelis said.
The background
To ease congestion in the area, crews constructed new frontage lanes and rebuilt the Williams Drive bridge to accommodate the DDI.
A DDI is a safer, relatively low-cost type of interchange that allows cars to pass through busy intersections more easily by eliminating the need for making left turns toward oncoming traffic, according to TxDOT. Drivers temporarily shift to the left side of the road when passing through a DDI in order to better the flow of traffic through the intersection and reduce the potential for T-bone and head on collisions, according to TxDOT.
Construction on the frontage roads includes a new section northbound from Williams Drive to Lakeway Drive. Going southbound from Williams Drive, additional lanes were built until the Hwy. 29/University Avenue intersection, according to city of Georgetown documents.
The cost
The $61.7 million project is funded by the Capital Area Metropolitan Planning Organization and TxDOT.
