I-5 - SR 161/SR 18 Triangle Improvements

Quarterly Project Report Update for Quarter Ending June 2005

Project Title & Location
I-5/SR 161 I/C & SR 18 I/C

Project Description
The I-5/SR 161/SR 18 Interchange Improvement project (Triangle Project Phase 1) includes replacing a cloverleaf loop ramp with a flyover ramp for WB SR 18 to SB I-5 traffic and provide a new WB SR 18 connection to SR 161. The I-5/SR 18 cloverleaf interchange is defined as a High Accident Location. Eliminating one of the loop ramps will eliminate the weave on WB SR 18 and SB I-5. These improvements will improve traffic flow and safety.
