The path would connect the Class I bike path along Bair Island Road and the Class II bike lanes on Main Street. The US 101 Pedestrian Undercrossing Project consists of a joint -use pedestrian and bicycle path under the US 101 freeway bridge at Redwood Creek. The proposed path will meet Class 1 bicycle path criteria. This 14feet wide path will be dedicated for use by both bicyclists and pedestrians. The path will be approximately 700feet long (246 feet within Caltrans right of way) and will pass under the US 101 freeway bridge between the northern bridge abutment and Redwood Creek. There will be approximately 9 to10 feet of clearance between the path surface and the soffit of the bridge.A "battered ground" anchor wall would be implemented on the abutment side, and a cantilevered retaining wall would be installed on the creek side of the path. The top portion of the wall between the path and the creek would utilize a 1 -foot high metal railing, which would allow passing pedestrians and bicyclists to have views of the creek. Landscaped retaining walls would extend beyond both entrances to the path under US 101.
