Project Description: In April 2012, Arapahoe County and its partnersColorado Department of Transportation, Denver Water and the City and County of Denver completed the trail underpass that allowspedestrians and cyclists on the HIgh Line Canal Trail to travel under Iliff Avenue, instead of fighting traffic in an attempt
to cross the major roadway.
Traffic flow is smoother, as motorists no longer need to stop to accommodate pedestrians and bicyclists crossing Iliff Avenue.As part of the project, sidewalks were extended over the High Line Canal on the south side of Iliff.
