The Connecticut Department of Transportation (CTDOT) has unveiled a $402 million proposal to overhaul the platforms and trainshed at New Haven’s Union Station, the busiest rail hub in the state.
The plan would rebuild and lengthen the platforms and build a full-length canopy that would stretch end to end above the tracks. Below ground, the proposal also calls for rehabilitating the passenger tunnel that connects the historic head house to the platforms.
Some residents have pushed back on plans to overhaul the tunnel, urging CTDOT to preserve its character. The project manager said the agency would consider the feedback.
Officials say the work is meant to extend the station’s service life while modernizing the passenger experience, with the new canopy designed to shelter riders from the elements year-round. To keep the station running through it all, CTDOT plans to phase construction one platform at a time so day-to-day rail service is uninterrupted.
Above the four rebuilt platforms, which vary in length, the trainshed would feature an arched central atrium framed by lower angled canopies on either side, creating continuous coverage that would eliminate the need for individual heated shelters on each platform. CTDOT renderings position the atrium as the station’s new architectural focal point, designed to function as a city landmark. The atrium’s design draws inspiration from Vienna’s Central Station, according to Zuhair Hussaini, an architect on the project.
The plans, which are about 30% complete, could change before construction begins, according to CTDOT. The project is still in the design phase and would be financed through a combination of federal and state funds. Construction is expected to begin in the spring of 2029, contingent on funding availability and permit approval. The phased build is intended to preserve service for Amtrak, Metro-North Railroad and CTrail, while also keeping the station accessible for Peter Pan and Greyhound bus passengers as well as riders using the free downtown shuttle.
The platform overhaul is distinct from but closely tied to the $316.1 million transit-oriented development announced at Union Station in June 2025. Under that earlier project, CTDOT selected Gilbane Development Co. and Mural Real Estate Partners to build two 16-story mixed-use towers on underused state-owned land adjacent to the station, according to CTDOT.
Together, the two efforts represent more than $700 million in planned public and private investment around a single transit hub. CTDOT has framed the work as part of a broader push to convert state-owned parking parcels into transit-oriented neighborhoods, with similar projects either underway or under consideration at sites in Stamford, Branford, Darien, Fairfield, Stratford, Wallingford, Waterbury, West Haven and Wilton.
