The Project will construct a new bridge to connect the existing sections of Notre Dame Boulevard over Little Chico Creek. The new structure will accommodate two 12-foot travel lanes separated by a 6-foot-wide center median, eight-foot bike lanes, a five-foot sidewalk on the west side and an eight-foot multi-use path on the east side.  The new bridge is anticipated to be a multi-span structure, approximately 100 feet long and 56 feet wide. The structure type is expected to be a three-span, cast-in-place, reinforced concrete bridge with 30-degree skew, a 2.0% Cambered 20” thick concrete deck, and will include rock slope protection at the banks under and adjacent to the bridge. In addition to the bridge, the existing bike path on the south side of the creek will be re-routed to a new bridge undercrossing and connect to the multi-use path crossing the bridge.

 

Construction of the bridge will involve excavation for and construction of concrete abutments and piers, founded on either spread footings or deep foundation. Other temporary work within Little Chico Creek includes falsework erection and removal, and installation of scour countermeasures at the support locations. Little Chico Creek is a seasonal creek and construction is anticipated to proceed without the need for a temporary water diversion system.  Construction of the roadway approaches will involve the removal and realignment of a portion of the existing bike path on the south bank. The approach roadway will tie into the existing curb, gutter, and sidewalk on the north and south portions of Notre Dame Boulevard. Approach roadway work will include both median and parkway landscape per city standards as well as street lighting and public utility extensions crossing the creek.

 

In accordance with the California Environmental Quality Act (CEQA), the draft Initial Study was made available for public review from October 18, 2022 through November 18, 2022.
