The U.S. Department of Energy (DOE) proposes to repair a pedestrian bridge and correct a drainageway that is between the Solar Energy Research Facility (SERF) and Field Test Laboratory Building (FTLB) at the National Renewable Energy Laboratory (NREL) South Table Mountain (STM) campus located in Golden, Colorado.

The existing pedestrian bridge crosses the middle drainage and provides a pathway between the SERF and FTLB. The bridge has deteriorated to the point that it is unsafe for pedestrians to use the bridge and has subsequently been closed for use. Additionally, flooding has eroded some of the drainageway under North Loop Road because water drains under the culvert instead of through it. The proposed project would address the repair needs of the bridge and correct water flow through the culvert. This project would not result in any change in the use, mission, or operation of the pedestrian bridge or drainageway.
