Roundabouts Coming to 403 Interchange

Reconstruction work at the Highway 403 and Rest Acres Road (Highway 24) interchange is underway, with provincial officials aiming to improve traffic flow and safety through the installation of new roundabouts but a lack of clear communication is leaving many local residents frustrated.

The project, led by Ontario’s Ministry of Transportation (MTO), will replace existing ramp terminals with two roundabouts, while also realigning ramps and upgrading drainage, landscaping and lighting infrastructure. The work is intended to accommodate increasing traffic volumes and support future employment land development in the area.

Pre-construction activity began in mid-March, with clearing work now complete and construction in progress. Intermittent ramp closures are scheduled for April 13 to 17 between 7 a.m. and 5 p.m., with motorists advised to expect delays and monitor updates through the provincial 511 service.

According to information shared by the County of Brant through its Engage Brant mailing list, impacts on Rest Acres Road are expected to be minimal, though occasional traffic flagging may occur. Ramp closures will generally take place on weekends for shorter durations, with some longer closures anticipated.

Despite those updates, many residents say the information has been inconsistent and difficult to access.

Concerns have been raised about the absence of a clear construction schedule, including which ramps will be closed and when closures will occur. Some closures have taken place during peak travel times, adding to congestion for residents already navigating multiple construction projects in and around Paris.

There has also been criticism over the lack of advance signage along the Highway 403 corridor warning drivers of upcoming ramp closures.

The Paris Independent contacted the County of Brant for additional details. While noting the project is being led by the province, County staff confirmed the municipality will contribute up to $12 million toward the project. Of that amount, $10.8 million will be funded through development charges, with the remaining $1.2 million coming from the capital levy over a 10-year period. The contribution is included in the County’s capital budget and long-term financial plan.

Questions regarding construction timelines, staging and overall project completion have been directed to the MTO. As of publication, the ministry had not responded to requests for comment.

It remains unclear how long construction will last, though the project is expected to span multiple years. In the meantime, residents are being urged to plan ahead, anticipate delays and check for updates before travelling through the area, while many hope communication from the province improves as construction progresses.
