Spring Creek Overpass

The Spring Creek Overpass will provide direct, safe access for pedestrians and cyclists traveling between the Natural Resources Research Center, the University Mall/Whole Foods shopping center, and MAX Bus Rapid Transit's Spring Creek Station. The structure will feature switchback-style ramps on both the east and west sides of the bridge, allowing travelers to easily (and safely!) transverse the railroad tracks.


The overpass was designed with accessibility and cost-efficiency in mind. The east and west ramps meet all Americans with Disabilities Act (ADA) requirements and reduce ongoing maintenance costs by offering simple, non-mechanical access for all users.

Just as at all MAX Bus Rapid Transit stations, the Spring Creek Overpass will feature 24-hour video surveillance and safety lighting.


The overpass will be built in two stages.

Phase 1: Summer 2013 - Fall 2013
The ramps and abutments will be constructed
Phase 2: Late 2013 - Early 2014
The bridge portion of the overpass will be built to connect both sides

Concrete Express, Inc. has been contracted to build both components of the overpass.

Requirement and Funding

A grade separated crossing at this location is required as part of the City's Operating Agreement with the Burlington Northern Santa Fe Railroad prior to the operation of the MAX BRT system. Additionally, the Federal Transit Administration grant approval for MAX was predicated on system ridership that assumes access to the businesses on the west side of the railroad tracks. The overpass meets these requirements and contributes to accessibility of the Spring Creek Station -- it will facilitate much needed pedestrian connectivity in the area. The overpass is funded by a grant from the Colorado Department of Transportation and the North Front Range Metropolitan Planning Organization.

Troutman Underpass

Construction of the Troutman Underpass is complete. This crossing provides safe and accessible passage under the BNSF railroad tracks and the BRT guideway. It connects the Mason Trail and MAX BRT's Troutman Station with the surrounding neighborhood.


Ramps on both sides of the underpass are designed in accordance with the Americans with Disabilities Act standards. A landing is provided at every 2.5 feet of vertical change in height. In addition, the underpass structure itself includes an 8 foot wide concrete path on both sides of a center pier to provide safe, accessible, and convenient access to pedestrians, bicyclists, and physically disabled users.
