A dashcam clip circulating among Cannondale neighbors this summer shows a near-miss at the Pimpewaug Road and Route 7 intersection, a driver cutting hard across four lanes at the unsignalized crossing. It is the kind of video that gets forwarded in group texts and then forgotten. But the corner it captures is not going away. For the next year and a half, it is the busiest unsignaled crossing in Wilton, and it happens to be the exact spot where the town's own trail planners chose to end the next mile of the Norwalk River Valley Trail.
That overlap is the real story this fall, not the bridge closures themselves. Two separate Metro-North rail bridges went into simultaneous reconstruction this year, and both projects are pushing detour traffic toward the same unsignaled intersection at the same time the trail's next extension is supposed to arrive there.
Two bridges, one funnel
The Cannon Road Bridge over the Norwalk River closed on June 3, 2026, and is expected to stay closed for approximately 18 months while the span is removed and rebuilt, according to Wilton's Department of Public Works. The bridge sits inside the Cannondale Historic District, about a quarter mile east of Route 7, and it dates to 1956, built as a two-lane crossing with a curb-to-curb width that predates the traffic it now carries. Access to the Cannondale Train Station is being maintained throughout construction, but the road itself is gone for a year and a half.
At almost the same time, the Honey Hill Road Bridge went into its own reconstruction. Connecticut's Department of Transportation approved both projects to proceed on overlapping schedules, citing cost savings from doing the work together rather than staggering it. That decision means Wilton is absorbing two major detour patterns in the same stretch of town, in the same construction season, rather than one at a time.
The Pimpewaug Road and Route 7 intersection
Both detours push traffic toward Pimpewaug Road where it crosses Route 7, a four-lane stretch with no traffic light. Wilton officials asked the state for a temporary signal there before construction began. According to Good Morning Wilton's reporting, the request was denied twice. Police Chief Tom Conlan told the outlet the department could see early on that Pimpewaug Road "as a possible detour was going to be challenging."
Residents who live along the alternate route have been more direct. As Good Morning Wilton reported, one neighbor said the town's suggested detour to Sharp Hill Road "misses three of four schools, the YMCA, the entrance to town center, Comstock, and numerous sport fields." The comment describes how the suggested detour would affect access to schools and services.
The trail's own extension ends at the same corner
Here is the detail that makes this more than a traffic story. The Norwalk River Valley Trail's Wilton Loop currently runs about 2.4 miles off-road on its east side, from the Wolfpit Road and Route 7 trailhead north to just short of Skunk Lane, largely along an elevated boardwalk through wetlands. The next phase, a roughly 0.9-mile extension funded by a $3 million state grant secured through the Local Transportation Capital Improvement Program, is designed to carry that trail from Skunk Lane north to Pimpewaug Road, according to Wilton Bulletin's coverage of the project's wetlands review.
The quiet wooded path that Wilton has spent years building out, engineered specifically to keep hikers and dog walkers off the roads, is scheduled to reach Pimpewaug Road, where the detours are also directing traffic. The trail was designed as an escape from traffic; its next mile meets the overlapping detours.
What still works this fall
None of this touches the parts of the loop that already exist. If you are walking, running, or biking the NRVT this month, the following sections remain open and unaffected by either bridge project:
- Merwin Meadows Park, reached from the pedestrian bridge over the tracks at the Wilton Metro-North stop, where the trail runs past the site of the former Dana Dam, removed from the river in September 2023
- Schenck's Island, along River Road through the town center, part of the west side loop
- Allen's Meadows, at the north end of the loop on Olmstead Hill Road
- The Wolfpit Road and Route 7 trailhead and boardwalk, the 2.4-mile off-road east side stretch that ends short of Skunk Lane
The Wilton Loop is projected to total 10 miles once fully connected. As of the most recent trail updates, roughly 6 miles are built out. The section under active tension is the last mile, the one meant to close the gap toward Cannondale.
Three projects, overlapping detours
Layer one more project onto this. An Aquarion Water and Eversource gas main project along New Canaan Road, Route 106, has its own detour running through October 2026, according to Wilton's public works announcements. That project began years earlier and is now in a new phase of excavation and paving that happens to close out at the same time the two bridge projects are just getting started.
For a town of Wilton's size, three concurrent construction detours sharing the same handful of connector roads is not a scheduling coincidence anyone chose. It is what happens when independently funded, independently timed infrastructure projects land in the same construction season by circumstance rather than design.
What this means if you live near Cannondale or walk the trail regularly
If your daily routine touches the Cannondale side of town, plan around a corridor that will not return to normal until sometime in 2027 at the earliest, and residents who track the project closely have raised concerns the real timeline could stretch closer to 20 months. If your trail habit is the wooded, quiet kind, the existing 6 miles from Merwin Meadows through Schenck's Island to Allen's Meadows are unaffected and will stay that way through the bridge work. The last mile toward Pimpewaug Road is worth watching, not walking through, until construction on both the bridges and the trail extension clears.
The town requested a signal at Pimpewaug and Route 7 before construction began, and the state denied the request twice. The intersection remains part of the detour picture for commuters and trail users this year.
