Project Summary
Staging and traffic control design related to roadway and bridge improvements in Hinckley, MN. The project is to replace two bridges over the BNSF railway, two bridges over the Grindstone river, repair Hwy 48 bridge over I-35, and construct an unbonded concrete overlay on I-35 for both the northbound and southbound lanes along with the reconstruction of the on/off ramps for Hwy 48 in Hinckley. A staging plan is needed to provide a diverted flow of traffic for the construction to be conducted in an efficient and safe manner. A detour plan is needed while the ramps at Hwy 48 are closed and under construction.
Design Goal
Design a staging plan, which will be used to create temporary traffic control concepts to implement while the roads are under construction. These plans will minimize impacts on the public and maximize worker safety and productivity. The detour plan is to be constructed in a way that minimizes the delay to the driver and focuses on the safety and wellbeing of the user. Increased levels of traffic for intersections is to be assessed and to make changes where necessary to keep the intersection levels of service above an F. Safety and efficiency are the most important factors for construction and traffic.
Design Constraints
- Intersections: Keep level of service above a grade F during construction.
- Traffic Volumes: High recreational traffic during summer months on weekends.
- Detour Routes: Provide alternative routes to the city of Hinckley and Highway 48.
- Bridge Construction: Must account for additional time to complete bridge construction.
- Hinckley Residents: Mitigate the traffic congestion for locals.
