Bridge Nos.06787 & 06788, which carry Rt.207 (Pond Rd.) over Beaver Brook, Franklin

The Department of Transportation (Department) will conduct a Public Information Meeting concerning the rehabilitation of Bridge Nos. 06787 and 06788, which carry Route 207 (Pond Road) over Beaver Brook, in the town of Franklin (Town).  Project No. 52-91 involves the slip-lining of Bridge Nos. 06787 and 06788.  Both pipe culverts were originally constructed in 1960.  Bridge No. 06787 is located approximately 100 feet east of the western most intersection of Bailey’s Hollow Road and Route 207, and Bridge No. 06788 is located at the intersection of Bailey’s Hollow Road, Under Mountain Road, and Route 207.  Each bridge supports one eastbound and one westbound traffic lane.  The existing structures are both two-cell, 72 inches in diameter, asphalt-coated corrugated metal pipe (ACCMP) culverts.  Each bridge has headwalls and wingwalls at both the inlet and outlet.  Bridge No. 06787 has a total pipe length of 282 feet and Bridge No. 06788 has a total pipe length of 95 feet.


     At this time, the project is nearing completion of the Preliminary Design phase.  The proposed work is to slip-line both two-cell 72 inch diameter pipe culverts with 64 inch outside diameter (60 inch inside diameter) corrugated aluminum pipes.  The annular space between the existing and proposed pipes, as well as any voids located behind the existing pipes where backfill exfiltration has occurred, will be filled with low-pressure grout.  The existing headwalls and wingwalls at both bridges will be repaired.  Cutoff walls will be constructed at the inlet and outlet of both bridges to prevent scour.  A shallow weir will be installed across the western inlet barrel of Bridge No. 06787 to direct water to the low flow western pipe.  At Bridge No. 06788, a shallow weir will be installed across the eastern inlet barrel to direct water to the low flow eastern pipe.  Additionally, access roads and staging areas will be constructed at both ends of each culvert to facilitate construction.  The access roads located in the State’s Right-Of-Way may be permanent.

     During construction, traffic on Route 207 can be maintained in the existing lanes.  Temporary single-lane closures may be used in order for construction vehicles to enter and exit the access roads.

     Environmental permitting will be required for this project.  Both of these bridges are located within a CTDEEP Natural Diversity Database screening area.  Proper erosion and sedimentation controls will be installed in an effort to maintain existing turbidity levels.  Right-of-way impacts for Bridge No. 06787 include temporary construction easements from six private property owners for work at the inlet and outlet, as well as work at the failed culvert along Bailey’s Hollow Road.  Right-of-way impacts for Bridge No. 06788 include temporary construction easements from two private property owners adjacent to the bridge for work at the inlet and outlet.  A permanent easement or small partial take may be required to allow for future maintenance of the southeast wingwall at the inlet of Bridge No. 06787, as a 2-foot long section of the wingwall is currently outside of the State’s Right-Of-Way.

     Construction is anticipated to commence in summer 2020 and be completed by fall 2020, assuming availability of funding and receipt of any required environmental permits or Right-Of-Way acquisitions.  The estimated construction cost for the project is $1,000,000 and will use State and Federal funds.

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

     Plans 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.

     All persons interested in this project are welcome to attend this meeting and discuss this project with Department personnel.
