High Line Canal Trail Underpass - Colorado/Hampden

Currently, the High Line Canal Trail leaves pedestrians and people on bikes at Colorado Boulevard and Hampden Avenue, a busy intersection that can be intimidating to cross on foot or on a bike. This project will build two underpasses to reroute the trail under Colorado and Hampden to create a safer, more convenient connection for people walking and riding bikes. In addition, between the two underpasses, Denver will add a new, 10-foot wide multi-use trail along the north side of Hampden.
