TRACK 2

Tremaine Road Extension from Steeles Avenue to No. 3 Side Road, Milton, Ontario: Managing Complex Environmental Challenges Through Careful Planning and Monitoring

Wednesday March 20, 2019
9:30 to 10:00 am

PRESENTERS

Peter van Driel and Derek Stewart, WSP Canada Group Ltd.

ABSTRACT

To accommodate increasing population growth in the Town of Milton, Ontario, the Regional Municipality of Halton is planning and constructing an improved transportation corridor for Tremaine Road, with a new interchange at Highway 401. This presentation showcases environmental management strategies used during construction of a portion of this corridor, between Steeles Avenue and No. 3 Side Road, involving a new alignment for Tremaine Road, with a grade separation at the Canadian Pacific Railway, built through the site of a historic shale mining and brick works operation.

This project required careful planning to address the environmental sensitivity of the surrounding landscape, including wetlands, woodlands, a new bridge over Sixteen Mile Creek, which is a coldwater fishery, plus three smaller tributaries, near and below the Niagara Escarpment. This area includes lands regulated by the Niagara Escarpment Commission, and in this same area, excavation of the CPR grade separation has generated approximately 150,000 cubic metres of excess soil, shale, and bricks, of which a significant portion is contaminated with heavy metals and polycyclic aromatic hydrocarbons.

 

Learning Objectives

1. Erosion and sediment control in an environmentally sensitive area.

2. In-water works and creek channel design.

3. Development of an excess soil management plan in a Brownfield site.
