    Ridge Avenue Bridge

    Ridge Avenue Bridge Replacement Project

    Montgomery County, in conjunction with the Ohio Department of Transportation, the City of Dayton and the County Engineers Association of Ohio, is replacing the existing Ridge Avenue Bridge over the Stillwater River.

    This project will replace a two-span steel girder bridge constructed in 1927 with three spans of prestressed concrete I-beams on reinforced concrete wall type abutments and wall type piers.  The project includes the installation of a left-turn lane from westbound Ridge Avenue onto Riverside Drive and a left-turn lane from eastbound Ridge Avenue onto Riverside Drive.  The new bridge will provide 10’ wide sidewalks, an improvement over the current 6’ sidewalks on the structure.  The project will also include improvements to the existing bus stop located at the southeast corner of Ridge Avenue and Riverside Drive.

    Location:

    This project is located on Ridge Avenue which crosses over the Stillwater River in the City of Dayton.  This bridge extends between DeWeese Park to the North, Triangle Park to the South and Riverside Drive to the west.

    Ridge Avenue is an urban collector, carrying approximately 4,900 vehicles per day.

     

    Closure/Detour:

    Ridge Avenue between Riverside Drive and DeWeese Parkway will be closed to traffic during construction and detours will be in place for vehicular, canoe and pedestrian/bike traffic.

    Work will begin on the project on Monday, February 17, 2014. 

    The bridge will close to vehicular traffic on Tuesday, February 18, 2014 and remain closed until September 2015. Ridge Avenue will be closed between Riverside Drive and DeWeese Parkway during the construction.  The detour route will begin just north of the bridge.  The detour route will be north on Riverside Drive to Siebenthaler Avenue, east on Siebenthaler Avenue, and south on Ridge Avenue. 

    The Stillwater Bikeway under Ridge Avenue will be detoured during construction beginning Monday, February 17, 2014 and remain closed until September 2015. The detour will begin just north of the bridge.  The detour route will be on DeWeese Parkway, across Ridge Avenue, along the south edge of the parking lot east of Ridge Avenue, and onto the Great Miami River Trail.  Bicyclists can then follow the Great Miami Trail south back to the Stillwater River Trail at the bikeway bridge to Island Metro Park. 

     

    Existing Structure:

    The existing bridge has a sufficiency rating of 45.1 (structurally deficient) and a general appraisal rating of 4 (poor/serious).  Conditions noted at the time of the bridge inspection included advanced section loss, deterioration, spalling, and scour.  The superstructure and substructure each received a “poor condition” rating and the deck received a “critical condition” rating.  Retaining walls on the eastern approach are in poor condition.  The guardrail on the east approach to the bridge has several areas of damage.

     

    Proposed Structure:

    This project will replace a two-span steel girder bridge constructed in 1927 with three spans of prestressed concrete I-beams on reinforced concrete wall type abutments and wall type piers. The three bridge spans are: 61’ – 89’ – 61’. Ridge Avenue will be realigned between Riverside Drive and DeWeese Parkway to soften the curve and to transition from two lanes to three lanes on the bridge.  The roadway will be 35’ wide with 10’ wide sidewalks.  The project provides an opportunity to undertake other improvements to the benefit of area residents and motorists. The project includes the installation of a left-turn lane from westbound Ridge Avenue onto Riverside Drive and a left-turn lane from eastbound Ridge Avenue onto Riverside Drive. The project will also include improvements to the existing bus stop located at the southeast corner of Ridge Avenue and Riverside Drive.

     

    Costs:

    Bids were taken for the project on January 8, 2014 and the contract was awarded to Brumbaugh Construction Inc. of Arcanum, Ohio on February 11, 2014 for $5,283,170.00.  Federal funds were secured for the construction of the project through the County Engineers Association of Ohio.  $4,901,191.55 is funded with Federal Funds and $381,978.45 is funded with Montgomery County Engineer Funds.
