Upcoming Projects
State Project No. 0108-0196: Construction of a Portion of the Quinebaug River Trail (Part of the East Coast Greenway) in the Town of Plainfield
This project includes the construction of a 1.6-mile long, 10-ft wide segment of multi-use trail starting at the intersection of Route 205 and South Walnut Street, turning onto CTDEEP property, then connecting with Trout Hatchery Road (SSR 426), and terminating at the intersection with Cady Lane. Completion of this segment of proposed muti-use trail will improve recreational opportunities and enhance non-motorized mobility and quality of life for both local and regional residents.
This project is anticipated to be advertised in the Summer of 2026 with the RFP to follow in approximately 3 months.
State Project No. 0131-0214: Replacement of Bridge No. 01241 Jude Lane, Bridge No. 01242 Route 229 (West Street), and Bridge No. 01243, Curtiss Street over I-84, in the Town of Southington
This project includes the replacement of three bridges (Bridge Nos. 01241, 01242 and 01243) which span I-84 in the Town of Southington. The purpose and need of the project is to address structural deficiencies and improve the safety, reliability, and capacity of the existing bridges through bridge replacement. The new bridges will be designed to have a minimum service life of 75 years, significantly improving long-term safety and reliability. The existing structures were constructed in 1963. Bridge No. 01241 is a multi-span structure with prestressed concrete girders and a concrete deck. Bridge Nos. 01242 and 01243 are multi-span structures with steel girders and concrete decks.

State Project No. 0063-0726: Rehabilitation of Bridge 01469B (Dutch Point Viaduct) I-91 SB in Hartford
This project consists of the rehabilitation of Bridge No. 01469B (Dutch Point Viaduct) which carries three lanes of southbound Interstate 91 traffic over the Connecticut Southern Railroad (CSRR), SR 598 Westbound and TR803 in the City of Hartford.

State Project No. 0079-0245: I-691 EB to I-91 NB Interchange Improvements in Meriden and Middletown
This project is located on a segment of Interstate 91 (I-91) that provides access to Interstate 691 (I-691), and East Main Street in the City of Meriden. The project limits begin on I-91 NB from the junction of the on-ramp from Route 15 NB (MP 19.6) to the Middletown rest area (MP 21.42) for approximately 1.8 miles. The project limits begin on I-691 EB off-ramp (MP 0.02) and extend to its junction with I-91 NB for approximately 0.4 miles.
The purpose of this project is to reduce congestion for the traffic movement at the left-handed off-ramp from I-691 EB to I-91 NB and along I-91 NB mainline and address associated safety concerns within the proposed project limits.
The proposed improvements consist of widening the off-ramp from I-691 EB to I-91 NB (Interchange no. 11) to two lanes and the construction of an operational lane on I-91 NB from the on-ramp from Interchange no. 11 s and the Middletown rest area. Bridge No. 01837 will be widened due to the proposed improvements. The merge point of the I-691 EB and WB off-ramps will be re-aligned to improve traffic operations by providing additional storage and maneuverability for vehicles.
I-91 NB is proposed to be improved between the on-ramp from Route 15 NB and the Middletown Rest Area by adding an operational lane and widening Bridge No. 03051 (I-91 NB over Baldwin Avenue) to accommodate the additional mainline lane. The deck for this bridge is also proposed to be replaced. No right-of-way impact is anticipated as part of this project.

State Project 0156-0181: Replacement of Bridge Nos. 00161 and 00162, Interstate 95 over Route 745 (First Avenue) and Metro North Railroad
The purpose and need for the project is to address the poor condition of the steel superstructure and provide safety and operational improvements to address concerns with congestion and traffic operations on I-95 in the Town of West Haven. The project is anticipated to involve the removal and replacement of the six-span simply supported superstructure, piers, and abutments of Bridge No. 00162. The bridge will also be widened to accommodate an additional southbound lane. Widening of Bridge No. 00162 will result in the need for approximately 2,200 feet of roadway reconstruction along I-95. The acceleration lane along I-95 southbound from interchange 44 (Route 10) across Bridge No. 00163 will be extended as an operational lane and transition to a deceleration lane for interchange 43 (Route 122).
To address the substandard superelevation through the curve within the project limits, the roadway reconstruction will be extended an additional 800 feet (for a total project length of approximately 3,000 feet), including Bridge No. 00161, which will require replacement. The Project also involves coordination of overhead high voltage lines and Metro North Railroad. Environmental permits are to be determined. No right-of-way impacts are anticipated as part of this project.
This Project is not anticipated to include a Project Labor Agreement (PLA).
