Figure 1 Noyes Slough Bridge in winter
We are working to replace the existing bridge (#0209) over the Noyes Slough located on Aurora Drive. Originally constructed in the early 1960s, the existing two-span 103 feet long and 36 feet wide bridge has multiple issues that make it undesirable to rehabilitate as opposed to replace. The bridge deck is in poor condition, and the center of the deck is supported by a pier that catches large amounts of floating debris and causes scour hazard. The sidewalk across the bridge is only 3 feet wide (2.5 feet wide at each end of the bridge) which is not ADA compliant. The current bridge profile also poses a safety issue due to inadequate sight distance for drivers using adjacent driveways and side streets.
The purpose of this project is to provide:
