Madison Street Bridge Rehabilitation

Underbridge info:

The pedestrian/bike underbridge below the Madison Street Bridge, which connects the Kim Williams river trail system, will be open until early May. At which point, the underbridge will be closed for safety reasons while crews remove and replace the bridge decking in the southbound lanes of the Madison Street Bridge directly above. Pedestrians and bikers will be able to cross via the newly widened sidewalk in the northbound lanes of the Madison Street Bridge. Pedestrians and cyclists are asked to please watch for signage concerning the closure and to not use the underbridge during the closure at any time. The underbridge will reopen with the completion of the Madison Street Bridge Rehabilitation in August of 2017.

For the week of May 1:

During the next few week drivers are asked to plan for delays, be aware of detours and to please watch for newly placed signage as Frontier West will soon be beginning the process of switching traffic from the southbound lanes to the newly rehabilitated northbound lanes. This transition will not take place for another 1 to 2 weeks, weather permitting and until then work on the new curb, sidewalks and railing the northbound lanes of the Madison Street Bridge will continue.

The right hand turn onto Front Street, when headed northbound, remains unavailable as crews work to complete the placement of new curbs and sidewalks in that area. Thank you for you patience.

With events taking place at the Adams Center and as traffic is reduced to 2 lanes on the bridge please plan extra travel time, expect delays due to congestion and, when possible, use alternate routes.

Throughout the duration of the project, there will be large openings due to the lack of decking in the northbound lanes. All pedestrians and cyclists are asked to not enter the work zone under any circumstances, day or night. Protective barriers have been installed to ensure that no debris falls from the bridge into the underbridge or the trail system below.

Trail System:
The trail system will remain open throughout the project with the exception of the trail access via Maurice Ave directly south east of the bridge.

For cyclists and pedestrians wishing to cross over the river via the Madison Street Bridge please plan additional time and watch for signage detailing new routes.

Project Overview

On November 21, 2016 work on the Madison Street Bridge support structures took place and on January 10, 2017 work on the bridge deck began with reduction of traffic down to two lanes and the removal of the bridge decking. Despite the cold weather delays in early January, the project remains on schedule.

Headed by general contractor, Frontier West, the primary goal of the Madison Street Bridge Rehabilitation is to fix the bridge’s failing bridge deck. In addition to bridge deck repairs, the project features structural, aesthetic and multi-modality improvements such new lighting and railings, bike lanes, and expanded protected sidewalks. Work also includes repair of the bridge’s support structures. The anticipated completion date of the Madison Street Bridge Rehabilitation is August 2017, weather permitting.

For the duration the Madison Street Bridge Rehabilitation Project, Frontier West recommends using alternate routes and encourages drivers to plan additional travel time, especially from 7:00 am to 9:30am and 4pm to 6pm, as there will be traffic delays on the bridge during these times.

Please obey all signage and remember that fines do double in work zones. Crews will be in operation Monday through Friday from approximately 8 a.m. to 5:00 p.m.
