State Route 29 Sulphur Creek and York Creek Bridge Rail Replacement Project

Sulphur Creek Bridge (BR# 21-0016) Napa County Route 29 PM 28.43

Work Description

  • Replace non-standard bridge rails with standard bridge rails.
  • A form liner for architectural treatment will be used to provide an appearance of stone.  The existing decorative street lamps will be reused along with the historic plaques.
  • Crash cushions will be installed at the bridge approaches.
  • Additional right of way will be required.

Sulphur Creek Bridge Alternative 1

  • Proposed shoulders for this alternative are 8 feet and the southbound side and 4 feet on the northbound side.
  • This alternative will necessitate closure of the northbound lane in order to construct the barrier slab.

Sulphur Creek Bridge Alternative 2

  • This alternative proposes to widen the northbound side of the bridge by 4 feet.  This alternative provides standard 8-foot shoulders on both sides of the bridge.
  • This alternative provides enough space on the bridge for two-way traffic.
