MnDOT releases 2013 Transportation Highlights Video
St. Croix Crossing, Hasting bridges are among featured projects
ST. PAUL, Minn. – This week the Minnesota Department of Transportation released its 2013 Highlights video that features several projects started or completed last construction season. The four-minute production includes a blend of work performed in the Minneapolis/St. Paul metropolitan area and a variety of Minnesota communities, including International Falls, Moorhead and St. Cloud. The video can be viewed online at www.mndot.gov.
Minnesota’s statewide multimodal system is featured in video segments that include freeways and highways, freight, aviation, bicycling and pedestrian projects. The video also details cost- and time-savings, while providing specifics on flexible design and unique construction processes used to stretch transportation dollars and reduce impacts to business and traffic.
Video highlights include:
- Hastings/Highway 61 Bridge – An innovative construction method minimized disruption to motorists and kept the old bridge largely open to traffic, avoiding the need to create a very lengthy and disruptive detour. The new bridge was constructed on the banks of the Mississippi, floated downstream and lifted into place.
- Highway 15, CR 120 in Sartell and St. Cloud Diverging Diamond Interchange – MnDOT introduced to Minnesota this new type of roadway interchange, which crisscrosses traffic across bridges and eliminates hard left turns. Diverging diamonds have proven to reduce traffic delays by as much as 60 percent, provide more capacity than a standard interchange and improve safety by creating better sight distance at turns and eliminating conflict points.
- Twin Cities maintenance – MnDOT maintenance crews implemented full freeway closures on Interstate 35 and I-94 to tackle multiple maintenance projects simultaneously. This helped maximize project efficiencies, savings and safety while significantly reducing traffic disruptions. The alternative would have been multiple lane closures over several months.
- Highway 169/I-494 Interchange – This project received a national award for demonstrating transportation efficiency while promoting economic and fiscal responsibility. It is an example of MnDOT’s move toward performance-based flexibility in design, which seeks practical and lower-cost ways to achieve targeted levels of performance improvements. In this case, MnDOT eliminated low-volume ramps so the interchange was reconstructed with six connections instead of the traditional eight, saving taxpayers more than $20 million while meeting more than 90 percent of motorists’ needs.
