I-16 WB FROM I-75 TO WALNUT CREEK - PHASE V

under construction

Phase 5 consists of 2.69 miles of capacity and operational improvements to I-16 westbound from I-75 to Walnut Creek (milepost 0.00 to 2.69). The Spring St. loop ramp will be reopened in Phase 5 and the northbound Spring St. left-turn lane to I-16 Westbound will be eliminated, restoring Spring St. to its current (pre-Phase 1) lane configuration. A new entrance ramp from Second Street to I-16 westbound will be added with this phase. Phase 5 will also complete the ultimate build-out of the west-to-north ramp from Phase 3 through the I-16 / I-75 interchange and will connect the north-to-east ramp with the work from Phase 2. These last two items will extend along the I-75 corridor from milepost 166.39 to 167.35 for a distance of 0.96 miles.
