US 101/Hearn Avenue Regional Multimodal Interchange

ongoing

The US 101 Hearn Avenue Regional Multi-modal Interchange Project will demolish and reconstruct the Hearn Avenue interchange overcrossing in the same location to increase vertical clearance over US Hwy101, widen the overcrossing to provide two vehicle lanes in each direction, a median, sidewalks, and two Class IV bike lanes extending to Corby and Santa Rosa Avenue. The project will also widen the southbound US 101 off-ramp with turning lanes at its intersection with Corby Avenue, add lanes at the intersections of Hearn Avenue/Corby Avenue and Hearn Avenue/Santa Rosa Avenue, and add pedestrian curb ramps and crosswalks that comply with the American Disability Act and incorporate protected intersection facilities for bike crossings and detection to reduce potential conflicts between bikes and vehicles. The project is the final phase of the Hearn Avenue and Santa Rosa Avenue Complete Streets Project to provide roadway widening, pedestrian, and bicycle improvements intended to improve mobility in southern Santa Rosa.
