There are many other examples of cast-in-place barriers being used in the lower mainland. The portion of HWY 1 between Brunette Ave. and Galardi uses cast-in-place... then changes to pre-cast :lol: Did they run out of money or something?? Also, portions of the new HWY will have cast-in-place barriers, but only very small portions. My guess is to save on costs. BC MoT definitely cheaped out.Pre-Cast barriers have been used in the Canadian Province of British Columbia since the 1950s. First generation barriers are about 60 cm in height, while ones used as median barrier on motorways, can be up to 120 cm in height.
Cast in place type barriers were used previously, but only as part of a retaining wall combo. Examples still exist on abandoned sections of the original Fraser Canyon Highway (Predecessor to the Trans Canada Highway) and a section of the Pacific Rim Highway on Vancouver Island
The province of Alberta also uses pre-cast barriers, but they are mostly used at major roadworks to protect construction crews. Sometimes they are used as a median barrier on major highways/motorways.
