Hwy 210 Bridge in Thomson
- On Hwy 210 between Carlton and Thomson over the St. Louis River
- June 6 to December 12, 2012
- Original cost for the rehabilitation project $1,924,078
- The updated cost, which includes flood-related repairs and the new bridge, appears to be approximately $2.75 million. All invoices have not been submitted or approved, the final cost is still being determined.
Although the Hwy 210 bridge reopened last December, there is about a month of finishing work left to be done.
The finishing work, which includes concrete surface finishing, placement of an epoxy chip seal on the bridge deck and painting, began on Monday, May 13. The work is expected to be completed by June 14.
- A temporary signal system is in place that restricts traffic to a single-lane on the bridge. Motorists are required to obey the signals and take turns crossing. The single-lane traffic configuration will remain in place until the project is finished in mid-June.
The project included
- Structural steel repairs or reconstruction
- Gusset plate replacement or reconstruction
- Replacement of riveted connections with bolted connections
- New expansion joints
- New concrete bridge deck and rail
- Concrete repairs/patching on the bridge abutment and wingwalls
- Bridge painting
- New concrete approach panels
Planned work should provide a 50-year life extension for the bridge.
