HICKMAN ROAD OVER TUOLUMNE RIVER BRIDGE REPLACEMENT
The contractor is MCM Construction, Inc. in collaboration with NV5 and is located near Waterford in Stanislaus County, California. The existing Hickman Road Bridge, constructed in 1946, runs over the Tuolumne River. It is 652.9 feet long and 33.5 feet wide and is constructed of reinforced concrete.

The replacement bridge will consist of a 750-foot long cast-in-place post-tensioned box girder with two 12-foot wide travel lanes and two 8-foot wide shoulders. It will be
constructed immediately upstream of the existing structure in order to keep the existing road and bridge open to public traffic during construction. The new bridge will be the same height as the existing bridge but 15-feet wider.
Disturbed soil areas will be stabilized during construction with temporary erosion controls and stormwater protection measures like:
Fit grading the surrounding terrain.
Time grading operations to minimize soil exposure.
Retaining existing vegetation whenever feasible.
Mulching disturbed areas.
Minimizing the length and steepness of slopes.
Preparing drainage ways and outlets to handle concentrated runoff until permanent drainage structures are constructed.
Trapping sediment onsite.
Diverting water from the top of disturbed slopes.
Placing BMPs so that diverted water is safely directed to an inlet, temporary conveyance, or vegetated area.
