Santa Cruz Marathon road closures: Which streets will be affected Sunday and when

An estimated 4,000 participants will flock toward the Santa Cruz Beach Boardwalk and race along the coastline on Sunday for the inaugural Santa Cruz Marathon. A side effect of the event is several planned road closures throughout the course, lasting until festivities conclude and roads are clear. These will be conducted on a rolling basis, with all affected roads expected to reopen by noon as the final runners cross the finish line. Traffic control personnel will also direct residents across the course as soon as it is safe to do so. The affected roads and hours are: Beach Street: Pacific Avenue, Cowell Beach and Boardwalk area — This is the start line; heavy traffic is expected.
