Highway 101: Summerland will add a peak-period carpool lane in each direction for 1.7 miles. At the Evans Avenue Undercrossing, a new bridge segment will connect the freeway bridges and be accompanied by pedestrian, bike lane, and lighting improvements underneath Highway 101.  At the Sheffield Drive Interchange, new freeway bridges will be built along with new right hand on- and off-ramps on southbound Highway 101 and improved northbound on- and off-ramps. The on-ramp at Wallace Avenue will be replaced and a new retaining wall will be added to accommodate the wider freeway.  There are also two new sound walls.

The timeline is a reference tool to show planned improvements and key closures.

 The timing may change to accommodate modifications from the contractor, weather delays, and to improve construction.

 Construction will begin in fall 2020 and continue with landscaping throughout 2023. Highway 101 will have 2 lanes open in each direction during daytime construction. There will be nighttime closures with signed detours as needed.
