Sudbury's Rail Trails Are Built. This Fall, the Work Moves to Their Edges.

At the Diamond Crossing near Union Avenue, two rail trails now meet in Sudbury. The Bruce Freeman Rail Trail runs 4.4 miles north to the Concord line. The Mass Central Rail Trail crosses it heading west for 4.3 miles of Sudbury wetlands and pine barrens. That Sudbury stretch is part of a 7.5-mile section through Hudson, Stow and Sudbury that DCR and Eversource opened with a ribbon cutting at the Diamond on July 16.

The pavement is done, but the places where the trail meets the rest of town are still being worked on: road crossings, a truck driveway, a parking-lot ramp, a few parking spaces near the Diamond. The Town's late-summer memo and the Rail Trails Advisory Committee's August minutes are almost entirely about these spots. One of them is also why the Bruce Freeman still has no grand opening date.

The Ramp Holding Up the Ribbon Cutting

MassDOT has signed off on construction of Phase 2D. It handed maintenance of the Bruce Freeman to the Town of Sudbury in July 2026. It made one exception. The accessible ramp and plaza at the Broadacres Farm parking lot on Morse Road still need handicapped-access fixes. According to Interim Rail Trails Coordinator Marcia Rasmussen's memo, MassDOT District 3 can schedule a formal opening once that work is done later this fall. As of the Town's September 24 update, no date had been set. The Town said it hoped for one later this fall.

The plaza has a second item waiting on it. The Friends of the Bruce Freeman Rail Trail commissioned a sculpture for Broadacres, and it's in storage in Sudbury until the plaza work is finished. The lot is already busy. The Sudbury Commission on Disability has run accessible biking programs there with All Out Adventures, and it got more funding in 2026 for additional events. Broadacres also has one of the trail's two accessible restrooms, paid for with a grant from the Friends. The other is at the Diamond.

So the trail is open, has restrooms, and already hosts programs. The ceremony is waiting on a ramp.

Crossing by Crossing

The two trails were built by different agencies, and their road crossings look different. MassDOT built the Bruce Freeman with yellow flashing lights at five road crossings, new traffic signals at Hudson and Peakham Roads, and a user-activated HAWK signal on Route 117. The Mass Central is managed by DCR, and its crossings don't all have those beacons. These are the spots that keep coming up in Town records:

1. Peakham and Hudson Roads on the Bruce Freeman. Concerns about how the signals are timed and coordinated keep coming back. The Town now owns those signals, and Public Works Director Tina Rivard has recommended a corridor study of Hudson Road to decide what to do next.
2. Busy Bruce Freeman crossings in general. Residents and drivers keep reporting walkers and cyclists who don't stop or press the flashing-beacon button. The committee worked with the Police Department and a graphic consultant on new yard signs along the trail that tell users to be safe and be seen by pressing the button.
3. Horse Pond, Peakham and Dutton Roads on the Mass Central. At the August 5 meeting, a resident asked whether these crossings could get Rectangular Rapid Flashing Beacons like the ones on the Bruce Freeman. Her concern was that drivers may not realize a major crosswalk is coming. The committee explained that DCR and MassDOT use different criteria for installing the lights. Her comments were to be passed to DCR Project Manager Amber Christoffersen. Separately, the Town says reports of cyclists crossing local streets without slowing or stopping for cars are rising, and it is contacting DCR about what may be needed to make the crossings safer.
4. The Cavicchio driveway. Committee Chair John Drobinski reported complaints that cyclists aren't yielding to trucks there. Another committee member proposed taking on one issue at a time with several strategies, starting with a warning sign at this intersection.

Why Fall Is When the Town Plans to Act

The August minutes treat this season as the time to change trail habits. Along with the crossing problems, the chair listed other frequent complaints: cyclists passing without warning, people walking three or four abreast, cyclists not stopping at intersections, and unsafe e-bike use. He also said e-bike legislation is moving forward and new limits on their use could come soon.

Here's what the Town has said it plans to do this fall:

• Rules signs. Standard Bruce Freeman rules signs are scheduled to go up this fall.
• Police and MassBike. The Sudbury Police Department plans to work with MassBike on education sessions, outreach toolkits for trail users, and more website and social media resources. Police Lt. Perodeau wants to work with the committee on these issues.
• Officers on the trail. Some committee members want police presence and education in the fall, when more students use the trail. The minutes note this approach seems to have worked in Acton and other towns with busy trails.
• Maintenance. DPW staff have already cleared brush near intersections. A lighting contractor is now available to maintain the crossing lights, and a brush and leaf sweeper will go out this fall. If you see a broken fence or a fallen tree, report it. The Town turns concerns into work orders.

Maintenance is split between agencies too. The Town now looks after the Bruce Freeman. On the Mass Central, the Town handles only issues such as trees down across the trail, and all other maintenance is DCR's responsibility.

Parking at the Junction

The Diamond is where the two trails meet, and it has the least parking. The Town says recent improvements there created 9 to 10 marked spaces. The Friends' trail page, last updated in April 2026, lists six spaces plus two accessible spaces at Union Avenue. Committee members have been talking with owners of land along the Chiswick Park driveway about adding parking that would serve both trails.

If you want to ride both trails from a single car, Davis Field and Parkinson Field have more room than the Diamond. From either one, you take the Bruce Freeman south to the junction.

Coffee at Mile 3.05

The Mass Central's own trail guide puts Union Avenue at mile 3.05 of the Sudbury section. It says there's a coffee shop, food stores and restaurants a quarter-mile south, and it warns that the road is busy. The closest stop is Sudbury Coffee Works at 15 Union Avenue. It's open 6:30 a.m. to 3 p.m. on weekdays, 7 a.m. to 3 p.m. on Saturdays, and closed Sundays. It was posting daily soup specials as recently as October 3. On a Sunday ride, try Sudbury Point Grill at 120 Boston Post Road, which takes online orders and reservations through its website. It's worth checking the hours before you go.

West on the Mass Central, the Dutton Road crossing at mile 1.0 used to be the Wayside Inn train stop. The trail guide notes that Babe Ruth, who lived nearby, caught the train to Boston there. Longfellow's Wayside Inn itself is 2 miles south along Dutton Road. That detour runs through one of the Mass Central crossings without a flashing beacon, which is why the Dutton Road request matters.

The Next Edges on the Map

More trailheads and crossings are on the way. Engineering firm Fuss & O'Neill spent the summer on the 100% design package for Bruce Freeman Phase 3, which runs from Union Avenue south to the Framingham line. The plans include a new parking lot and trailhead on Nobscot Road and an accessible side path down to the old cattle pass under the railbed near the town line. The firm expects to file with the Sudbury Conservation Commission later this fall. The Town's trail page says construction funding is in the regional Transportation Improvement Program for federal fiscal years 2029 and 2030. The Friends list a 2029 construction start.

To the east, the next Mass Central section is in design. It will extend the trail from its current end near Landham Road, over the Sudbury River, to the Mass Central in Wayland Center. Construction is expected to start in 2028. Each new section will add road crossings and parking lots, just like the ones the Town is working through this fall.

A new trailhead, a signal study or a planned parking lot near your street can change how buyers see your property. Bell Property Partners tracks those details in Sudbury along with the sales data. If you'd like to know how the trail network affects your home, request a complimentary home valuation.
