The City of Hamilton is planning to extend the Upper Red Hill Valley Parkway south of Rymal Road and Twenty Road East further east, connecting at a new roundabout.

The approved North Glanbrook Business Park Transportation Master Plan and Red Hill Business Park South Transportation Master Plan Addendum fulfilled the Phase One and Two requirements of the Class Environmental Assessment process.

The next phase of the study is currently underway in order to follow the Phase 3 and 4 requirements.

The city held public engagement sessions in both February 2021 and June 2025.

Staff are now confirming design options and will then finalize a draft environmental study report this fall.

That report will be presented to Hamilton City Council in Winter 2025, at which time a Notice of Study Completion will be issued, and public review will take place.

The extension would cut across a wooded area and agricultural fields, and the city says that some land may have to be acquired through expropriation.

Documents also indicate that the city may extend the Upper Red Hill Valley Parkway even further south in the future in what they call a “Potential Airport Conceptual Link Alignment,” but that would require a separate study.

A multi-use path would connect the Twenty Road East extension to Trinity Church Road.

The city says that previous studies “had identified capacity issues” on the existing road network in anticipation of increased traffic from the development of the Red Hill Valley Business Park.

Therefore, they say that extensions of both roads are needed in order to “service planned growth areas and developments within the Red Hill Business Park area.”

City staff have presented three possible design options for Twenty Road.

The first option is for a two-lane road with separated on-street bike lanes, 2.7 metres for street trees and streetlights and then sidewalks on both sides.

The first option is expected to cost $4.6 million.

The second option is for a two-lane road with a centre turning lane, 2.7 metres for street trees and streetlights, a multi-use path on the north side and a sidewalk on the south side.

The second option is expected to cost $5.0 million.

The third option is for a two-lane road with a centre turning lane, 2.7 metres for street trees and streetlights, a cycle track on both sides and sidewalks on both sides.

The third option is expected to cost $5.3 million.

Staff currently recommend the second option.

City staff have presented four possible design options for the Upper Red Hill Valley Parkway extension.

The Upper Red Hill Valley Parkway will have two lanes of traffic, but the city says that it will be widened in about 20 years to four lanes of traffic.

The first option is for two lanes of traffic with ditches on both sides and a multi-use pathway on the east side. That is expected to cost $20.7 million.

The second option is for two lanes of traffic with a centre turning lane, a sidewalk close to the road on the west side and a ditch and then a multi-use pathway on the east side. That plan would cost $16.5 million.

The third option is the same as the second one, except the sidewalk on the west side would be further from the road. That plan is expected to cost $17.7 million.

The fourth option is for one lane in each direction separated by a median ditch with a sidewalk on the west side and a multi-use path on the east side. That option would cost an estimated $26.0 million.

Staff currently recommend the second option.

The future intersection at Twenty Road East and Glover Road would be an unsignalized intersection with a two-way stop control on Glover Road.

The project would be implemented in phases, with the Twenty Road East extension to be built first.
