I-16 EB FROM I-75 TO WALNUT CREEK - PHASE IV

under construction

Phase 4 consists of 2.92 miles of capacity and operational improvements to I-16 eastbound from I-75 to Walnut Creek (milepost 0.00 to 2.92). Second Street will be widened from four to six lanes, and the Second Street overpass bridge will be reconstructed. A 10 foot sidewalk will be added to the east side of the Second Street bridge. Eastbound entrance and exit ramps will be added to Second Street with this phase. The Phase 4 improvements will complete the ultimate build-out of I-16 eastbound started with Phase 1. Within the main interchange, Phase 4 will also construct the remainder of the south-to-east ramp from Phase 3 and the remainder of the west-to-south ramp and north-to-east CD road from Phase 2.
