Connecticut Bridge Bundle
The Connecticut Bridge Bundle project consists of the design and construction of superstructure replacements and minor improvements for four bridges.
The bridges were all constructed in the 1960s and consist of cast-in-place concrete decks supported by simple span steel beams on concrete abutments and piers. The superstructures all exhibit significant deterioration and the substructures require minor patching and strengthening. The design-build team led by Middlesex replaced and re-paired 3 bridges in East Hartford and one bridge in Willington, including:
- I-84 WB (Exit 54 to Downtown Hartford) over I-84 EB in East Hartford (Bridge No. 02367)
- Route 2 WB (to Downtown Hartford) over I-84 EB in East Hartford (Bridge No. 02366)
- Route 2 EB (towards Norwich and New London) over I-84 in East Hartford (Bridge No.02369)
- Potter School Road over I-84 in Willington (Bridge No. 00847)

Scope of Work
- Full superstructure replacement of 4 bridges with composite steel girders that have a 75-year design service life and are designed in accordance with AASHTO LRFD
- Substructures for Bridges 00847 and 02369 – 20-year design service life
- Substructures for Bridges 02366 and 02367 – 75-year design service life
- Prefabricated Bridge Units (PBUs)
- GRS-IBS abutments – used to reduce the superstructures from three spans to single spans
Unique Challenges
- Using Accelerated Bridge Techniques such as PBUs to meet or exceed the schedule while minimizing impacts to the public
- Collaborating with CTDOT to design and build a model for future D-B projects in the state
