I-405/South Renton Vicinity Stage 2 - Widening (Nickel/TPA)
I-405 is highly congested between the I-5 and the SR 169 interchanges. This project constructs a new half-diamond interchange at SR 515, including an off-ramp from southbound I-405 to SR 515 and an on-ramp from SR 515 to northbound I-405, Adds a north and southbound lane on I-405 between SR 167 and SR 169, and reconstructs the Benson Road Bridge over I-405. These improvements will reduce congestion and improve efficiency.
