Trunk Highway 336 Connection
Glyndon Township, Minnesota

Project Details:
Houston Engineering performed construction staking for the Minnesota Department of Transportation (MnDOT) road construction project on the Trunk Highway 336 connection between U.S. 10 and I-94. Houston provided MnDOT’s contractor, Northern Improvement Company, with accurate, efficient, and timely staking for this project. Advanced Global Positioning System (GPS) survey equipment was used to accurately lay out the many complex curves for the ramps, new mainline road alignments, and frontage roads.

Over two million cubic yards of fill were hauled in for this multi-million dollar project. When construction was completed, Highway 336 was widened to four lanes between I-94 and Highway 10. The bridge over I-94 was expanded to four lanes, and bridges were built over Highway 10 and the adjacent railroad tracks with ramps allowing easy merging onto the highway.

The improved Highway 10 interchange makes it much easier to get on and off the road, which is a major advantage for moving traffic. Recent traffic counts show 7,600 cars each day travel on Highway 336 between Highway 10 and I-94, according to Tom Lundgren, MnDOT project manager. Projections indicate that 11,500 cars will be zipping across that corridor in 20 years. “We’re looking to protect the corridor so it processes traffic in a safe and efficient manner out into the future,” Lundgren said. “In addition, safety concerns about the intersection at Highway 10 and the nearby railroad crossing—where several accidents have taken place—are eliminated because traffic passes overhead,” he said. The project now allows traffic to flow even when a train is moving through the area.

Project Benefits:

• Accurate staking necessary for construction
   
• Timely, efficient staking provided by skilled personnel using the latest technology
   
• Fast completion due to addition of supplemental crews as necessary so as not to delay construction
   
• Safe, efficient traffic flow
