Public Info. Meeting - Bridge Nos.01218 & 04180, I-84 over Housatonic River, Newtown & Southbury

The Department of Transportation (Department) will conduct a Public Information Meeting concerning the rehabilitation of Bridge Nos. 01218 and 04180 which carry I-84 over the Housatonic River in Newtown and Southbury.   Project No. 96-201 involves the rehabilitation of Bridge Nos. 01218 and 04180 which are 4-span continuous plate girder structures supported by reinforced concrete abutments and piers that are founded on piles.  Bridge No. 01218 carries I-84 Eastbound over the Housatonic River and is known as the Rochambeau Bridge.  This structure was originally built in 1953 and reconstructed in 1979.  Bridge No. 04180 carries I-84 Westbound over the Housatonic River and was built circa 1979.  Both structures have an overall length of 792 feet and a curb-to-curb width of 60 feet.

The proposed project scope includes the replacement of the existing two-girder floor system with a steel multi-girder superstructure on both bridges.  The new superstructures will have the same out-to-out and curb-to-curb widths as the existing bridge superstructures.  Modifications to the existing abutment stems and construction of new pier caps on top of the existing pier walls will be necessary to accommodate the new multi-girder configuration.  Concrete repairs on Pier 3 of Bridge No. 04180 will be completed.  To facilitate demolition and erection operations, the construction of a temporary work trestle in the median between the two bridges is proposed.  The work trestle will be supported on temporary piles which will be driven into the river bed and will be removed or cut after construction.  Construction access will likely be from the temporary work trestle and barges.

Maintenance and protection of traffic will be accomplished by crossing one bound of I-84 over to one bridge while construction occurs on the adjacent bridge.  Two 12-foot wide travel lanes and 1-foot wide shoulders will be maintained in each direction while the crossover is in-place.  The sidewalk on Bridge No. 01218 will be closed for approximately two years while the demolition of the existing superstructure and construction of the new superstructure occurs.  Wayfinding signs will be placed directing cyclists and pedestrians to use the River Road #2 crossing over the Housatonic River.

Construction is anticipated to commence in the spring of 2020, assuming availability of funding and receipt of any required environmental permits or right-of-way acquisitions, and be completed in fall 2024.  The estimated construction cost for the project is $60,000,000 and will use Federal and State funds.

The Public Information Meeting is being held to afford a full opportunity for the publicís participation and to allow open discussion of any views and comments the community may have prior to progressing the proposed project into the Design Phase.

Conceptual drawings will be available for public review.  Department personnel will be available during the meeting to discuss this project.  More detailed information is available at the Department's Office of Engineering, 2800 Berlin Turnpike, Newington, Connecticut, during office hours, Monday through Friday, 8:30 a.m. to 4:30 p.m., excluding holidays.  Anyone wishing to review the plans may contact Mr. Andrew J. Cardinali, Transportation Supervising Engineer, at (860) 594-3315.
