Crews are making great progress on construction of the US 101/Blossom Hill Interchange Improvement Project. Modifications to the interchange include reconfiguring the highway on-and off-ramps, widening the Blossom Hill Road overpass over US 101, and creating new bike and pedestrian access. Upon completion, these improvements it will reduce congestion and increase traffic flow on Blossom Hill for all modes of travel, including bicycles and pedestrians. Construction is expected to be completed in Fall 2022.
