Sections of Interstate 494 will close this weekend as construction crews begin a major project to replace two bridges and remove several ramps. The Minnesota Department of Transportation (MnDOT) initiated the closures Friday night, impacting traffic flow in both directions.
The affected stretch of I-494 closed at 10 p.m. Friday and is scheduled to reopen Monday at 5 a.m. Drivers should anticipate significant detours during this period. The work marks the start of a long-term infrastructure improvement plan for the interstate.
Key Takeaways
- I-494 closed in both directions between I-35W and Highway 77.
- Crews are removing the Nicollet Avenue bridge and a pedestrian bridge at 12th Avenue.
- Eastbound and westbound Nicollet Avenue ramps to I-494 are permanently closing.
- The new Nicollet Avenue bridge is expected to open in September.
- Additional I-494 closures are planned for March, with work continuing until 2030.
Major Bridge Removals Underway
Work crews are focusing on two critical structures this weekend. The Nicollet Avenue bridge is being removed as part of the broader project. Additionally, a pedestrian bridge located at 12th Avenue is also slated for demolition.
The removal of these bridges is a complex operation requiring specialized equipment and extensive safety measures. MnDOT advises motorists to plan their routes in advance and use designated detours to avoid delays.
“These closures are essential for modernizing our infrastructure and improving safety for all commuters,” a MnDOT spokesperson stated. “We understand the inconvenience, but the long-term benefits will be substantial.”
Project Scope
- Bridges Removed This Weekend: Nicollet Avenue bridge, 12th Avenue pedestrian bridge
- New Nicollet Avenue Bridge Opening: Expected September
- Project Completion: Anticipated 2030
Permanent Ramp Closures Implemented
Beyond bridge removals, crews are also permanently closing the eastbound and westbound Nicollet Avenue ramps that connect to I-494. This decision aims to enhance safety and streamline traffic flow in the area.
These specific ramps have been identified as being too close to other existing ramps at Lyndale Avenue, Portland Avenue, and 12th Avenue. Their removal is a strategic move to reduce congestion and potential hazards caused by short merging distances.
Traffic Flow Improvements
The permanent closure of these ramps is part of a wider effort to optimize the interstate's design. By eliminating closely spaced entry and exit points, traffic engineers expect to see a notable improvement in vehicle movement and a reduction in accident potential.
Detour Information
During the I-494 closures, drivers are being rerouted onto Interstate 35W, Highway 62, and Highway 77. These designated detours are marked, and commuters should follow signage carefully. Real-time traffic updates are available through MnDOT's communication channels.
Long-Term Project Timeline
This weekend's work is only the initial phase of a multi-year construction initiative. More I-494 closures are already scheduled for March, indicating the extensive nature of the project. The overall construction along this section of the interstate is projected to continue until 2030.
The long-term plan includes a series of infrastructure upgrades, bridge replacements, and roadway improvements. These efforts are designed to ensure the longevity and efficiency of one of the region's most vital transportation corridors.
- Future Closures: Planned for March and subsequent months.
- Overall Project Duration: Expected to last until 2030.
- Goal: Improve safety, traffic flow, and infrastructure durability.
Local residents and daily commuters should prepare for ongoing traffic changes and plan their travel accordingly over the next several years. Staying informed about MnDOT announcements will be crucial for navigating the construction zones effectively.
