Replacement of Bridge No. 02719 in Middlefield, Route 147 over Lyman Meadow Brook

The Connecticut Department of Transportation (Department) will conduct a Public Information Meeting concerning the replacement of Bridge No. 02719, which carries Route 147 over Lyman Meadow Brook in the town of Middlefield (Town).  The meeting will be held on Wednesday March 26, 2014 at 7:00 p.m. at the Middlefield Community Center, 405 Main Street, Middlefield, Connecticut.  


This project involves the replacement of the subject bridge, which was built in 1920, and consists of an 8-foot clear span, cast-in-place concrete slab supported by stone masonry abutments.  The abutment foundation type is unknown.  The curb-to-curb deck width is 26.6-feet, which matches the approach roadway width.  There are two 12-foot travel lanes with very narrow shoulders.  There are no sidewalks on the bridge or approaches.  The out-to-out deck width is 29.3-feet.  

The proposed project consists of replacing the existing structure with a 12-foot wide by 5-foot high precast concrete box culvert, with one foot of natural streambed material placed in the culvert.  The proposed curb-to-curb width will be 32-feet, which consists of a 12-foot travel lane and 4-foot shoulder in each direction.  This replacement is necessary because the existing structure is structurally deficient and functionally obsolete.  Its structural deficiency is primarily due to the deteriorated condition of both the superstructure and substructure.  Its functional obsolescence is due to the substandard roadway width in relation to the existing volume of traffic utilizing this road.  The new concrete parapets along the structure will receive form liner aesthetic treatment to match the adjacent bridge along Route 147 presently under construction.  Roadwork will include replacement of the bituminous overlay (full and partial depth) for a minimum distance beyond each end of the structure.  Additionally, guiderail will be replaced and attached to the newly constructed bridge parapets.

A detour route around the project will be implemented to complete the construction. The proposed detour will be approximately 7.2-miles, utilizing all State routes. The detour will occur during the summer when school is not in session and last approximately one month. The majority of through traffic will not utilize the entire detour and will instead divert off toward their destination before completing the entire route.  The proposed water handling plan consists of utilizing a 36-inch temporary bypass pipe for approximately four weeks or a bypass pumping system so that all in-water work can be performed in dry conditions.  Temporary flow diversion structures will be installed across the channel both upstream and downstream of the bridge and the temporary pipe will pass under the roadway beyond the limits of the proposed culvert location.


Aerial utilities will have to be adjusted in order to implement the recommended replacement alternate.  Property impacts in terms of temporary easements and temporary work areas are anticipated.  There will be no permanent impacts to private property due to this project.

The proposed construction is anticipated to start spring 2015 and will be completed in approximately four months overall including utility relocation. The estimated construction cost of the project is $1.25 million.

The Public Information Meeting is being held to afford a full opportunity for public participation and to allow open discussion of any views and comments the community may have concerning this proposed project.  The meeting facility is ADA accessible.  Language assistance may be requested by contacting the Department of Transportationís Office of Communications (voice only) at 860-594-3062, at least five working days prior to the meeting.  Language assistance is provided at no cost to the public and efforts will be made to respond to requests for assistance.
