Fall River Road Bridge

Ulteig was hired by Colorado Department of Transportation (CDOT) to complete the design of the Fall River Road Bridge project. Begun as an urgent response to improve safety for bicyclists who used the busy westbound I-70 to access the Fall River community, the project evolved to a vehicular bridge, adding an alternate route for emergency vehicles on I-70 in heavy congestion such as peak ski travel season.

The project supports CDOT’s Whole System – Whole Safety initiative by improving safety conditions for all modes of transportation using I-70. The project design also accommodates
future greenway trail projects from the Clear Creek County master plan, avoiding the need for future modification.

An added challenge was revealed through stakeholder engagement with the local rafting community. Because the proposed bridge would be located almost directly above a rapid, the standard one-foot freeboard design for Clear Creek County bridges would not be adequate. Ulteig incorporated rafters’ goals by modifying the original design to accommodate a vehicular bridge with eight feet of freeboard.

This project was a powerful reminder to go beyond the “usual” stakeholders and ensure that a transportation solution truly embraces the needs and accommodates the impacts of the whole community. Without the extensive community engagement facilitated by Ulteig, this inclusivity would not have been possible.

This rural town in north-central Minnesota was overdue for several infrastructure repairs, including reconstruction of a one-mile stretch of highway into a segment of city street with a multipurpose trail and sidewalk. Glyndon’s 50-year-old cast-iron wastewater collection piping was also in need of replacement.

Ulteig was selected by the Clay County Highway Department and City of Glyndon to complete design and construction for this entire project. During 2017, work began with taking the main arterial rural section of roadway and converting it to an urban section by widening and lowering it, adding a curb and gutter system, and incorporating a sidewalk on one side and a bike path on the other. Utilities beneath the roadway had to be lowered and regraded since they did not meet cover
requirements. The water distribution system within the reconstruction area also required replacement to ensure sufficient storm water drainage.

When this major renovation is completed in 2018, it will dramatically improve pedestrian safety and traffic flow through town, making Glyndon a more appealing prospect for potential new businesses and homeowners.

This $5 million project for CDOT converted the existing signalized intersection at SH 340 (Broadway) and Redlands Parkway in Colorado to a roundabout. Ulteig provided construction management, inspection and public information services. The project’s top goal was to decrease accidents at the intersection, the vast majority of which were rear-end and left-turning accidents.

CDOT asked to keep the intersection open throughout project. The Ulteig team designed a temporary roundabout, which allowed traffic to continuously flow without stopping construction. The temporary roundabout also helped expedite the project timeline.

By eliminating the need for short-term traffic light signals and a reduction in other traffic control devices, the temporary roundabout design saved approximately $250,000. Most important, there were zero CDOT-reportable accidents when the temporary roundabout was in effect. The final roundabout has reduced the queue at the intersection from one minute, 35 seconds to 25 seconds.

Ulteig designed a first-of-its-kind pretreatment system for waste generated at a rest area along I-94 managed by the North Dakota Department of Transportation. This innovative system can be easily modified for almost any rest area location at half the cost of other treatment alternatives. During construction, Ulteig also made facility updates to meet new ADA accessibility requirements.

The project timeline was significantly compressed but completed on schedule, in order to address concerns from the U.S. Fish and Wildlife Service that the work might affect nearby nesting birds and migrating whooping cranes
