对这个项目的需求是由于不断增长的Fountain城市对从交通事故以及铁轨到车辆的距离的主要安全问题的关注所驱动的。该市于2009年通过了移动的喷泉远期税收计划，以帮助资助该项目。这项工作拆除了过时的铁路交叉口，并增加了一英里的新道路，起源于喷泉溪地区公园，然后越过BNSF和联合太平洋铁路线，并连接到Duckwood Road和美国85号的新信号交叉路口。

The project also helped the city create a quiet zone by removing the requirement for trains to honk their horns at urban intersections. The two rail companies were originally scheduled to install the new track crossings before completion of the roadway connections, but various track emergencies and weather events across the country slowed railway progress in Fountain.

The project team resequenced work to keep the project moving forward by building out the original Duckwood roadway first. However, during conduit boring for the new traffic signal, crews discovered a previously unidentified underground fiber optic line. Poor soil conditions and high ground water also added to the challenges.

Portions of the project were redesigned, and many construction variances were approved so that work could continue. The design includes optimized pavement sections and flexibility for future improvements. The completed project also includes a high-tech interconnect from the railroad crossing to the new U.S. 85 traffic signal that shuts down traffic turns when a train approaches the crossing. Multimodal improvements in the Duckwood segment included bike lanes and pedestrian ramps.
