WEST MAPLE STREET BRIDGE REHABILITATION PROJECT

BACKGROUND

The Maple Street Bridge over the Kinnickinnic River, being a structurally deficient bridge with a sufficiency rating less than 80, is eligible for bridge rehabilitation funds. The City of River Falls supports the notion of properly-timed maintenance and rehabilitation efforts to prolong the life expectancy of bridges. Significant delaminating of the deck was noted in 1998. Subsequent maintenance was done by the City of River Falls to remove and patch delaminated areas. Some of the removals were for the full depth of the deck. We anticipate that the rehabilitation of this bridge would involve scarifying and overlaying the bridge deck at a minimum ion addition to partial and full depth patching. On February 25, 2004, the City was notified that $258,400 had been approved in the 2005-2007 STP Local Bridge Program for rehabilitation of the maple Street Bridge. PROJECT FUNDING Federal funding will pay for 80% of the cost for this project. $258,400 has been approved in the 2005-2007 STP Local Bridge Program for rehabilitation of the Wasson Lane Bridge. The City of River Falls CIP for 2006 and 2007 includes proposed funding for the local 20% match.

PROJECT DESCRIPTION

Maple Street currently serves as a minor arterial street for the City of River Falls and plays an important role in the local transportation network. It is one of the main roads used to access the west side of River Falls. The bridge is located in the heart of downtown River Falls less than one block from Main Street. The current structure is not ADA compliant with regards to handicap accessible walks and should be corrected as part of the rehabilitation. Curb drop offs from the existing walks are also severe.

We anticipate that the rehabilitation of this bridge would involve scarifying and overlaying the bridge deck in addition to partial and full depth deck repairs as necessary. Rehabilitation work involving the bearings and abutments is also likely.

The proposed rehabilitation should be attractive and incorporate aesthetic treatments to the maximum extent allowable under the STP Local Bridge Program and within the planned budget. It is anticipated that the bridge will be closed during rehabilitation with traffic detoured to the Division Street Bridge.

SCHEDULE REQUIREMENTS

The project must be completed within the 2005-2007 STP Local Bridge Program timeframe. The City of River Falls CIP anticipates construction in 2007.
