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. The bridge consists of 33 spans with an overall length of approximately 1,800 feet, with a curb-to-curb width of 42’-0” and the out-to-out width is 47’-6”.

The purpose of this project is to upgrade the integrity of the bridge structural elements to a “state of good repair” to meet current design standards and improve the load carrying capacity, with the intent that all legal and permit vehicles are accommodated. It is anticipated that the project will involve deck replacement with precast panels, joint replacement (including longitudinal joint and elastomeric concrete headers), superstructure steel repair and strengthening, bearing repairs, spot painting, repair and strengthening of steel pier bents using micropiles, substructure patching and repair of the bridge drainage system. This project is within the levee protected flood zone X of the Connecticut River and therefore, it is not anticipated there will be a need for a Floodplain Management Certification.

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).
