Route 9 in Middletown

The largest project on the schedule, 0082-0318, is the removal of traffic signals on Route 9 in Middletown, classified as an expressway upgrade and scheduled for advertising June 23, 2027, in the $90 million to $120 million band. A related project, 0082-0330, "Roadway Improvements - Vicinity of RT 9," is listed as a breakout of 82-318 and is scheduled for Jan. 20, 2027, in the $2.5 million to $5 million band. Middletown is in Middlesex County, which has 1,038 DCP-credentialed contractors in this site's directory.

Wallingford design-build

Project 0148-0215 would replace Bridges 03129, 03130, 03131 and 03133 over I-91 in Wallingford. The schedule describes it as an RFQ for design-build, with the first step set for Feb. 10, 2027, in the $60 million to $90 million band. Design-build teams pair a contractor with a designer, so engineering firms and contractors would need to team up before the request for qualifications.

Rail and transit

Rail and transit projects make up a large share of the biggest jobs. The NHRY wheel mill truing shop in New Haven and Phase 2 of the New Haven Line Power Program between Westport and Greenwich are each in the $60 million to $90 million band. A new bus facility for the New Haven service area is in the $40 million to $60 million band. A SEAT facility in Preston, WRTD facility modifications and expansion in Windham, and Stamford MOE power are each $30 million to $40 million. The Madison railroad station (listed as SLE) and customer service improvements at New Haven Main Line stations are each $20 million to $30 million.

Highway and bridge

Other large highway jobs include the Bulkeley Bridge rehabilitation in Hartford, Route 82 safety improvements in Norwich ($30 million to $40 million), a mill and overlay on I-84 in District 1, bridge deck repairs in District 1, bridge coating in District 4 in two contracts, an operational lane on US 1 in Orange, and the Stonington and Groton maintenance facilities.

Who bids

CTDOT prequalifies its own prime contractors. Publicly funded building work over $1 million in designated classifications requires DAS prequalification instead, but state law excludes DOT highway and bridge work from the DAS program. See our CTDOT bidding guide and the Middlesex County and New Haven County hubs.
