Proposed interchange and realignment of I-5.

Overview
The project re-built the I-5/US 12 interchange at Grand Mound to improve mobility and safety. The modified interchange configuration of US 12 over Interstate 5  eliminated the loop ramps. Traffic signals were installed at both ramp intersections resulting in a typical "diamond" interchange configuration. On the east side of the interchange, the two existing exits from northbound I-5 are consolidated to one exit point.

How You Benefit
