Greenwich To Host Meeting On Repairs To Two Merritt Parkway Bridges

GREENWICH, Conn. -- As the state begins planning the work to rehabilitate two bridges that carry Merritt Parkway traffic over two brooks in Greenwich, the public is invited to inspect the plans and to offer input.

A public informational meeting on the plans will take place at 7 p.m. Tuesday, Nov. 19, at the Greenwich Town Hall, Cone Conference Room, 101 Field Point Road, the Connecticut Department of Transportation announced.

Plans will be available for public review at Town Hall. Department personnel will be available during the meeting to discuss this project. The public is encouraged to attend and offer comments.

Bridge No. 02135, which carries the Merritt Parkway over Converse Pond Brook, consists of a single-span concrete deck slab that is supported on concrete abutments, endwalls and wingwalls. It is located 100 feet north of Exit 28 on the Merritt/Route 15.

The bridge carries two northbound travel lanes and two southbound travel lanes with a deceleration lane. The roadway width is 80 feet. The northbound and southbound travel lanes are separated by a 21-foot-wide grass median.

The project will address the bridge’s structural deficiencies due to the poor condition of the outlet endwall and the outlet wingwalls, DOT said. The bridge is also hydraulically inadequate.

As part of the project, the Route 15 northbound shoulder will have 80 feet of full depth roadway construction due to the reconstruction of the existing headwall and wingwalls, DOT said.

The reconstruction of the endwalls, wingwalls and the increase in length of the Exit 28 off-ramp will result in 450 feet of full depth roadway construction along Route 15 southbound, DOT said.

The proposed lane and shoulder configurations will match the existing roadway layout when the work is complete.

The bridge rehabilitation will be constructed in two stages with the existing travel lanes maintained at all times during construction. Temporary access roads will be constructed off the Route 15 northbound and southbound right shoulders to provide access and egress to the culvert inlet and outlet.

The work, which will be paid for with federal and state funds, is anticipated to begin in summer 2015.

Bridge No. 02138, which carries the Merritt Parkway over Horseneck Brook, is located a half-mile west of the North Street overpass. The bridge consists of a single cell, cast-in-place concrete culvert and concrete endwalls and wingwalls, DOT said.

The 87-foot wide culvert carries two lanes in each direction, with the northbound and southbound lanes separated by a 20-foot wide grass median.

The project will address the culvert’s structural deficiencies due to the poor condition of the barrel walls and soffit, DOT said. The culvert is also hydraulically inadequate.

The proposed bridge rehabilitation will result in minimal roadway construction because most of the work will be performed off of the Merritt Parkway. Temporary access roads will be constructed to allow the contractor access and egress to the site.

The travel lanes on the Merritt will be maintained at all times during construction. The work, which will be paid for with federal and state funds, is anticipated to begin in summer 2015.

More information is available at the DOT's Office of Engineering, 2800 Berlin Turnpike, Newington, from 8:30 a.m. to 4 p.m. weekdays. To review the plans, contact Joseph Scalise at 860-594-3389 or Joseph.Scalise@ct.gov to make an appointment.
