I-5/SR 161/SR 18 - Interchange Improvements |
The interchange will be modified to eliminate the current ramp weave on southbound I-5 and westbound SR 18. This project will partially rebuild the I-5 & SR 18 interchange by removing the northwest cloverleaf ramp and replace it with a flyover ramp from westbound SR 18 to southbound I-5. A new direct connection from westbound SR 18 to SR 161 in the vicinity of S. 359th St. is included. This project will reduce congestion at the I-5/SR 18/SR 161 interchange and improve safety. |
