Half Moon Bay, CA – A much-used pedestrian bridge on the California Coastal Trail was closed on Monday, July 27, due to ongoing problems with its structural integrity. The bridge, on Mirada Road at Miramar Beach, will remain closed for at least a year, until a project to fully replace the bridge can be implemented.
The bridge is mostly within San Mateo County’s jurisdiction, with a portion within the jurisdiction of Half Moon Bay. The County determined that the bridge had deteriorated structurally to the point that it warranted an immediate closure, in the interest of public safety. The bridge links two sections of Mirada Road over Arroyo de en Medio, which is a seasonal creek. Over the years, the harsh marine environment and erosion have contributed to the deterioration of the concrete and other elements of the bridge to the point where it was deemed no longer safe to use.
Although it is unfortunate that the bridge was closed without advance notice, Half Moon Bay agrees that this is the appropriate decision.
“I understand and share people’s frustration with the sudden closure of the bridge, and the resulting disruption in use of the Coastal Trail there,”
said Half Moon Bay Mayor Adam Eisen.
“However, public safety must be the priority. I can assure the community that we will work with the County and other agencies so that a safe and clearly-marked detour is put in place, and that the replacement project moves forward as soon as possible.”
The replacement bridge project will include removal of the existing bridge’s decaying concrete archway and the bridge deck, strengthening the banks below the bridge, installing a new aluminum weather-resistant bridge structure, and taking necessary steps for slope protection of the bluffs adjacent to the bridge abutments. The City is in discussions with the County concerning possible cost-sharing of the project.
There are a number of issues contributing to the time it will take to replace the bridge: a project design and plan must be developed; a number of necessary permits must be obtained; and the work must take place after winter, to take into account weather and high surf issues. The City will continue to inform the community about a Coastal Trail detour and the replacement project, as progress is made.
