Kelley Square's peanut, five years on: a Worcester report card
The $16-million reconstruction of Worcester's most argued-over intersection turned a notorious six-way collision into a peanut-shaped hybrid roundabout. Five years in, the verdict — from drivers, from cyclists, and from the Canal District businesses on its edges — is mixed, evolving, and stubbornly Worcester.
For decades, Kelley Square earned its reputation honestly. The intersection where Vernon, Millbury, Water and Harding streets converged at the southeastern edge of downtown Worcester was, for years, ranked among the most dangerous intersections in the Commonwealth — at one point eighth statewide by crash counts. Anyone who learned to drive in central Massachusetts learned a particular kind of nerve at Kelley Square: the merging-without-stopping body language of a city that, on this one block, had simply decided rules of the road were optional.
That ended, more or less, in the spring of 2021. The $16-million state reconstruction project — engineered by MassDOT and timed to the opening of Polar Park — replaced the freewheeling six-way merge with a peanut-shaped modified hybrid roundabout. Two travel lanes, two compressed circles connected by a short straightaway, and a reordered network of one-way feeder streets: Millbury Street southbound, Harding northbound, Water and Vernon reorganized to channel traffic into the peanut at predictable angles. The signage matched. The geometry, finally, made sense.
What the data say
Five years on, the safety case for the redesign holds up. Crash counts inside the intersection have fallen sharply from pre-reconstruction levels, with the steepest drop in serious-injury collisions. The lowering of effective speeds inside the peanut — the entire point of a modern roundabout — has done what roundabouts everywhere are supposed to do: turn high-energy right-angle crashes into lower-energy glancing crashes. Pedestrian counts in and around the intersection have climbed. Cyclist counts, more modestly, have done the same.
Those are the headline numbers. The quieter numbers underneath them tell a more local story.
The Canal District perspective
The Canal District, which sits immediately southeast of Kelley Square, is the neighborhood the reconstruction was supposed to unlock. By most measures, it has worked. Pedestrian access from Water Street to the Polar Park gates is materially better than it was; the corner that once felt like a barrier between downtown and the ballpark now feels like a transition. New storefronts in the surrounding blocks have largely held; the long string of vacant lots along Harding has been gradually filling in.
The merchant complaints that surfaced during construction — about loss of frontage parking, about confusion in the early months — have largely faded. What remains is a genuine debate over how the peanut handles peak loads on game nights, when WooSox traffic, restaurant traffic, and through-commuters all hit the geometry at the same time. On those nights the peanut works, but it works at the limit of its capacity.
Drivers still hate it. Sort of.
If you ask a Worcester driver how Kelley Square works now, you will get a divided answer. Drivers who came up before the redesign tend to give it a grudging C-plus — better, but slower at peak, and the loss of the old "just keep moving" merging culture is, in a particular Worcester way, mourned. Drivers who learned to drive after 2021 mostly do not understand what the complaint is. Their Kelley Square is just an intersection; they navigate it the way drivers anywhere navigate a roundabout, and they are generally surprised to learn it used to be different.
What's next at the corner
The peanut is not the last word on Kelley Square. The city has been clear that future improvements — better cycle infrastructure connecting through the intersection, a refreshed Vernon Street streetscape, and additional crosswalk improvements on the southeast leg — are part of the longer plan. The reconstruction was always pitched as a first phase rather than a final state.
What the reconstruction has succeeded at, unambiguously, is reframing the conversation. Kelley Square is no longer an emergency. It is a corner that the city now argues about the way it argues about other corners — incrementally, in council meetings, in posts on neighborhood pages. That is a small upgrade. In an infrastructure project, it is also the upgrade that matters.
