Increasing traffic volumes, in conjunction with a short merge lane on westbound SR 500, created a high congestion area, which led to the potential for more collisions.
This project made improvements to westbound SR 500 in the vicinity of the I-205 Interchange to improve safety and reduce congestion. The improvements lengthened the merge lane beyond the interchange area to reduce the risk of accidents.
This project improved safety for drivers traveling westbound on SR 500 in the vicinity of the I-205 Interchange by extending the westbound merge lane beyond the interchange. The extended merge lane helps reduce the risk of accidents.
Increasing the length of the merge lane westbound on SR 500 promotes smoother traffic movement.
