The project is identified as State Project No. 0089-0129.
The purpose of the project is to rehabilitate Bridge No. 05002, which carries Ponus Ridge Road
over Collins Pond in the Town of New Canaan.
The existing Bridge No. 05002, built in 1957, carries Ponus Ridge Road over Rippowam River
(Upper Reach) in the town of New Canaan approximately 0.2 miles northwest of Clearview Lane.
The existing bridge is located approximately 45 feet downstream from the concrete masonry dam
and spillway of Collins Pond. The Federal Emergency Management Agency’s (FEMA) study
refers to the watercourse upstream of and through this bridge as the Rippowam River (Upper
Reach). However, the project title will indicate that the bridge carries Ponus Ridge Road over
Collins Pond to agree with the Department’s inventory of bridges. This single span structure is
36’-6” long with a span length of approximately 32 feet and carries one lane of traffic in each
direction with a curb-to-curb width of 22’-0”.
The proposed rehabilitation of Bridge No. 05002 involves replacing the existing superstructure
with precast concrete deck units topped with a 5-inch minimum thickness shear slab, a
waterproofing membrane and 3 inches of bituminous concrete. The existing abutments will be
modified to accommodate the new superstructure. The curb-to-curb width of the deck will be
increased to 24 feet wide to accommodate a 10-foot travel lane and 2-foot shoulder in each
direction. 42-inch vertical shaped parapets with stone cladding will be constructed on both sides
of the bridge to give a stone façade for the structure to improve aesthetics at the site.
The proposed rehabilitation will be accomplished during one construction season. The
maintenance and protection of traffic involves a full closure of Ponus Ridge Road at the bridge
and a detour of traffic. The proposed detour route is approximately 4.5 miles long and uses
Greenley Road, West Road and Dans Highway.
It is anticipated that Rights-of-Way impacts to private property surrounding the bridge will include
four permanent takes to keep the existing wingwall ends within the Town’s street Right-of-Way
and two temporary construction easements.
Construction is anticipated to begin in Spring 2023 based on the availability of funding, acquisition
of rights of way and approval of permits. The estimated construction cost for this project is
approximately $1.55 million. The construction of this project is anticipated to be undertaken with
80 percent Federal Funds and 20 percent Municipal funds.
