PROJECT DESCRIPTION

The Utah Department of Transportation (UDOT) in partnership with Logan City will install a pedestrian culvert undercrossing trail at 600S, located adjacent to the US-89 (Main Street) Bridge in Logan City. This underpass addresses a critical gap in the trail network, allowing for safe and uninterrupted movement between trails near the Logan River Golf Course and those extending toward Logan Canyon. It will improve accessibility and safety by eliminating the need for trail users to cross Main Street.
