Join Regional Parks along with Board of Supervisors Chairman and Third District Supervisor Dawn Rowe and Vice Chair and Fifth District Supervisor Joe Baca, Jr. on Thursday, Feb. 12, from 12-1 p.m. to celebrate the completion of the SART Phase III with a ribbon-cutting ceremony and first official ride out onto the trail afterwards.
The completion of Phase III represents significant progress in advancing the SART project, which will eventually result in a complete path from the National Forest boundary in Mentone to the Pacific Ocean in Huntington Beach.
With the completion of Phase III, 11 miles of trail now makes it possible to walk or bicycle along the river from a spot north of California Street, through all of San Bernardino and Colton, and nearly to the western end of Riverside.
“Regional Parks is excited to complete this section of the Santa Ana River Trail bringing us 3.8 miles closer to the mountain crest. This will increase recreational opportunities for our users to bike, hike, walk or use as a means of alternate transportation that provides them a safe road of travel away from road traffic,” said Beahta Davis, director of Regional Parks.
Regional Parks is responsible for the creation, operation and maintenance of the eventual 22 miles of trail within the county when Phase IV is completed.
