DescriptionThis $207 million design-build project will reconstruct and widen over 12 miles of I-35W from County Road C in Roseville to Lexington Ave (County Road 17) in Blaine. Roadway improvements include widening to accommodate an additional MnPASS lane in both directions of I-35W, adding auxiliary lanes in multiple locations, reconstructing or reconfiguring 13 interchanges, and constructing an Unbonded Concrete Overlay (UBOL) over significant portions of the existing roadway. In addition, the project will reconstruct five bridges; install seven noise walls; construct a closed median drainage system and associated water treatment facilities; upgrade interchange and roadway lighting, signing, and striping; and implement an Intelligent Transportation System (ITS) to support the new MnPASS facility. The project includes a significant focus on Maintenance of Traffic (MOT) to ensure the 105,000 to 136,000 vehicles that pass through the work zone do so in a safe and efficient manner.
As prime design firm on the Ames Team, Alliant is responsible for leading the following design disciplines: project management, roadway, MOT, drainage, structures, environmental design and compliance, traffic design, ITS, and design surveys.
