Birch Street is a city right of way that crosses over the Loutsenhizer Canal near the Black Canyon Golf Course. Over the years, the bridge’s abutments and supporting foundations had become undermined and its supporting soils were eroding away. The undermining had advanced enough that replacement of the bridge became warranted.
The bridge was replaced with an aluminum box culvert similar to those present on city rights of way over the Loutsenhizer Canal at Otter, Niagara, Sunnyside, and Miami Roads. The project also replaced an undersized and aged waterline and failed sewerline beneath the bridge.
