Bridges: Underpass

As our urban trails become more widely used, and our streets more congested, safe street crossings have become increasingly important. LORIS has designed numerous trail under-crossings of busy streets and highways. We understand the critical design issues ranging from safety, to utility relocation, to construction phasing. Phasing is one of the primary considerations of building underpasses because, in most cases, the street being crossed must remain fully operational during construction. And, similar to our bridges and structures, we like to incorporate aesthetics into our underpass designs. The following selected projects represent a cross-section of LORIS' capabilities in pedestrian underpass design.

		Wonderland Creek Underpass Boulder, Colorado
		Van Bibber Creek Trail Crossing at Ward Road Arvada, Colorado

		Truscott Drive Underpasses at SH 82 Aspen, Colorado
		Skunk Creek Underpass at Broadway Boulder, Colorado
		U.S. Highway 287 Underpass Broomfield, Colorado
