AUSTIN, Texas — The intersection at Interstate 35 and Parmer Lane is changing soon. Community Impact reports that crews are expected to complete construction on the intersection by early October.
The new intersection will use the "diverging diamond" strategy. Drivers will temporarily switch lanes when Parmer Lane crosses I-35 so drivers will drive on the left side of the road. The design allows for through and left-turning traffic to move through the intersection at the same time.
A Texas Department of Transportation spokesperson told Community Impact that after the bridge is in the diverging diamond intersection configuration, crews will construct the median island across the bridge, finalize pedestrian elements and install and complete drainaige, wastewater and "high-mast illumination."
TxDOT will also reconstruct the North Lamar Boulevard and Parmer Lane intersection. That part of the project includes implementing right-turn lanes and dual left-turn lanes from Parmer to North Lamar. The entire project, which costs $24.6 million, is expected to be completed early next year.
Community Impact reports that the diverging diamond design has already been implemented at I-35 and RM 1431, and TxDOT is also working on a diverging diamond intersection at Williams Drive and I-35. That project is expected to be completed in mid-2023.
