This division of responsibilities and fiscal control leads to conflicts and inconsistencies in operations and in the formulation and implementation of long-range plans. [...] The British Columbia Ministry of Transport is responsible for planning and coordination of highways and other modes of transportation throughout the province. [...] Detailed plans are necessary because the effects of tolls are sensitive to the topology of the road network as well as the demographic characteristics of the area. [...] As proposed by the Consulting Engineers of British Columbia , the best option to intercept a large fraction of traffic in the GVRD appears to be a network of tolls on the 22 major bridges and tunnels in the region. [...] Also similar to Montréal, the most heavily used link in the region, the Port Mann Bridge near the western end of the TransCanada highway, is to be replaced and 40 tolled.
