Following a rockfall at Dewitt Hill on the evening of May 10, 2026, the City, in
collaboration with Hamilton Police and community safety partners, made the decision
collaboratively to close Dewitt Road while the area is assessed and secured.
Hamilton Police and City Transportation staff attended the site promptly following
reports of the rockfall. There were no reported injuries or fatalities, no damage to
vehicles and minimal roadway impact as the existing concrete barriers prevented
significant effects on the right of way.
Given the immediate proximity of the rockfall to the railway corridor, Canadian Pacific
Railway has been notified. Minor debris cleanup within the rail right of way has already
been completed in coordination with the Railway Authority, and any additional
remediation, stabilization, or repair work required within or adjacent to the corridor will
continue to be completed in collaboration with CP Rail.
The City’s third-party engineering consultant inspected the site Monday afternoon to
assess the escarpment face and provide recommendations on the stability of the
rockface, whether additional stabilization work is required, whether current safety
barriers remain sufficient in the short term and if additional protective measures should
be considered before the road reopens.
Dewitt Road will remain closed for the remainder of the week as the required interim
remedial rockface measures have been completed, and the fallen rock debris has been
removed. Timing to reopen the road will be predicated on the measures and actions
needed to be taken to ensure it is safe to travel on Dewitt Road.
The City will continue working closely with all relevant agencies and technical experts to
ensure public safety and will provide updates as more information becomes available.
Motorists are encouraged to use alternate escarpment access routes while Dewitt Road
remains closed. Delays should be expected in the area until the roadway can be safely
reopened.
