State Route 99/Eaton Road Interchange Improvement Project

Environmental Documents

Post

The proposed project would convert State Route 99 northbound ramps at Eaton Road and Hicks Lane into one multi-lane five-leg roundabout intersection.

The proposed project would convert State Route 99 (SR 99) North Bound (NB) ramps at Eaton Road and Hicks Lane into one multilane five-leg roundabout intersection. Although the two intersections would be combined, the local circulation and access would remain unchanged. The primary purpose of the proposed project is to improve safety for all travel modes at the SR 99 NB ramp intersection and Hicks Lane intersection with Eaton Road. The secondary purpose of this project is to improve operations, reduce delay, and enhance mobility for all travel modes at the intersections.  Construction would be phased in order to maintain local access to SR 99 and to the properties adjacent to Eaton Road and Hicks Lane.

The public comment period for the Draft Initial Study/Proposed Negative Declaration (IS/ND) was open from August 26, 2019 through September 25, 2019.
