Avon, Connecticut is moving forward with a full replacement of the Tillotson Road Bridge over Thompson Brook, taking on one of the small but costly infrastructure fixes that have piled up across the state for decades.
The project reflects a challenge that extends well beyond this quiet Hartford County suburb. Connecticut consistently ranks among the worst states in the nation for bridge condition, earning a C- on the American Society of Civil Engineers' most recent state infrastructure report card. Of the more than 617,000 bridges in the United States, roughly 42,000 are classified as structurally deficient, and Connecticut carries more than its share. Most of the country's bridges were built during the highway-building boom of the 1950s through 1970s and are now simultaneously reaching or exceeding their designed lifespans.
Small-town bridges like this one are especially vulnerable to neglect. They carry lower traffic volumes than state highways, so they rarely rise to the top of priority lists, yet they are far too expensive for a single town's annual budget to absorb without outside help. Avon, despite being one of the wealthier communities in the state with a population of around 18,000, faces the same structural fiscal pressure as every other Connecticut municipality: 169 independent towns, no county government, and a heavy reliance on local property taxes to fund capital projects.

The timing of Avon's decision to replace rather than repair the bridge likely reflects both the urgency of the structure's condition and the availability of new federal money. The 2021 Bipartisan Infrastructure Law directed $40 billion nationally toward bridge repair and replacement, and Connecticut is receiving approximately $561 million over five years through the law's dedicated Bridge Formula Program. The state's Local Bridge Program also provides aid to municipalities for exactly this kind of project. Similar federal investments have funded bridge replacements in communities across the region, including a $4.4 million bridge replacement on Route 1 in Stafford County, Virginia.
The specific cost of the Tillotson Road project and its funding sources have not been disclosed publicly. The town has posted the solicitation on its bids page through the Town Manager's office as it seeks contractors to carry out the work. Once a contractor is selected and a contract awarded, more details about the project timeline and cost are expected to become clearer.
