The new Port Mann Bridge will be a single 10-lane span, with three through-lanes in each direction and two lanes in each direction dedicated for local access to and from Surrey and Coquitlam. Once the new bridge is built, the existing five-lane crossing will be removed.

The new Port Mann Bridge will consist of three key sections:

• Cable‐stayed main bridge across the Fraser River (850 metres). This portion will be constructed using steel girders which support pre‐cast concrete deck panels, and will have an asphalt road surface. This section of the bridge will be supported by two centre pylons or towers, rising 160 metres from the water, and can be divided into the:
• The main span (470 metres)
• The south span (190 metres)
• The north span (190 metres)
• South approach, Surrey (350 metres) ‐ constructed using 327 pre‐cast concrete sections with an asphalt road surface. 
• North approach, Coquitlam (820 metres) ‐ constructed using 831 pre‐cast concrete sections with an asphalt road surface.
