The Dumbarton Bridge, which connects Menlo Park in southern San Mateo County with Fremont in the East Bay, remains the only bridge that allows bicyclists and pedestrians to cross the San Francisco Bay from east to west, with an eight-foot wide path on its southern side. From the bridge, the path continues for three miles along Bayfront Expressway (Highway 84) through Menlo Park to Marsh Road. It’s an important biking and walking connection for both commuting and recreation.
Poor maintenance of the bridge path and Bay Trail by Caltrans, however, continue to discourage use. The bridge path is not swept often enough to keep it free of glass and other debris, which reduces the usable width of the path from the minimum eight feet required by Caltrans’ own Highway Design Manual. Occasionally, large objects such as car bumpers and plastic buckets litter the path. From mid-May to mid-June, large piles of highway debris blocked a two-foot section of the path. The culprit? After the roadway was cleaned, the garbage that had accumulated there was dumped onto the car-free path. Though the large items littering the path have been removed, glass shards and dirt remain.
John Fox, who has commuted by bike from Fremont to Stanford University for the last 13 years, finds the bumpy, pothole-filled conditions of Marshlands Road, used to access the bridge from the East Bay, a greater challenge. “That road is horrible, it’s like a cheese grater,” he said. “In the winter time a lot of us ride until dark, and then it’s pretty dangerous.”
