Hover Street Pedestrian Underpass Longmont, Colorado

Promoting active transportation and pedestrian safety, the Hover Street Pedestrian Underpass is located just south of the street’s intersection with SH119. With Otak leading structural engineering, the design included relocating a Regional Transportation District (RTD) bus pad directly on top of the underpass to further enhance safety while improving multimodal access.

A Structure to Enhance Pedestrian Safety and Multimodal Access

In designing the overpass, a “jug handle” link trail was used to divert the flow of traffic to allow seamless, safer turns that don’t require crossing oncoming traffic. Named for its distinct shape, this design also allowed for the creation of a plaza area with bike lockers and other site amenities. The project’s emphasis on multimodal access is highlighted by a bus pad located on top of the overpass. Key aesthetic features include multiple concrete formliners and pilaster columns with masonry veneers found on the underpass and headwalls. A detention facility was also added to manage drainage from SH 119 and adjacent business property. Accounting for a complex intersection geometry and high traffic volumes, the project was constructed using a three-phase maintenance of traffic approach.
