ALTERNATIVES

During the development of the functional design study four alternatives have been proposed for detailed evaluation, these include shifting PTH 1 north, PTH 1 on the same alignment, shifting PTH 1 south, and separate interchanges for PTH 16 & PR 305.

Alternative A: PTH 1 Shift North

download Alternative A

Pros

• No intersections on PTH 1 or PTH 16
• CN Railway and PTH 1 overpasses closer together, requiring less fill on PTH 16
• Minimizes disturbance to wildlife habitat

Cons

• Major property impacts including removal of one residential farmyard
• Potential stream channel re-alignment (PTH 1)
• Potentially disruptive to know sensitive habitat

Alternative B: PTH 1 on Existing Alignment

download Alternative B

Pros

• No intersections on PTH 1 or PTH 16
• Utilize existing PTH 1 Eastbound lanes and Rat Creek crossing for Service Road
• Property impacts minimized
• Minimizes disturbance to wildlife habitat

Cons

• Potential stream channel re-alignment (PTH 1)

Alternative C: PTH 1 Shift South

download Alternative C

Pros

• No intersections on PTH 1 or PTH 16
• Utilize existing PTH 1 Eastbound lanes and Rat Creek crossing for Service Road
• Configuration of Westbound to Northbound Ramp and Southbound to Westbound Ramp minimizes width for CN Railway overpass structures
• Minimizes disturbance on Rat Creek
• Eliminates direct access to PR 305

Cons

• Close to suspected environmentally sensitive habitat
• Potential impact to one residential farm yard

Alternative D: Separate Interchanges for Highways 16 & 305

download Alternative D

Pros

• Simplifies traffic operations at PTH 16
• Potential benefit for access to industrial park
• No intersections on PTH 1 or PTH 16
• Re-uses existing PTH 1 Eastbound lanes and maximizes re-use of PTH 1 Rat Creek crossing for Service Road
• Property impacts minimized at PTH 16
• Minimizes impact on wildlife habitat

Cons

• PR 305 realigned
• Requires steam channel re-alignment (PTH 1)
• Potential impacts to three residential farmyards
