Rundle LRT Station/36th Street NE Pedestrian Bridge
Calgary Transit completed an upgrading of the platforms at six LRT stations on the NE line to accommodate 4-car trains.
A component of Phase II of the NE Station Redevelopment project was the replacement of the existing pedestrian bridge at Rundle LRT Station.The existing pedestrian bridge connected the upper level of the station head via ramps and stairs to the at-grade sidewalks on the east and west side of 36th Street NE.
Read Jones Christoffersen was the bridge engineer for preliminary engineering, contract documents and resident engineering for the new bridge crossing.
The preliminary engineering phase considered various alignments and profiles for the bridge and ramps.
The close proximity of adjacent properties on the east and west sides of 36th Street, define a small footprint for landing the ramp and stair connections to grade.Optimum ramp slopes to comply with current accessibility standards have been incorporated into the design, and these have been located to align with existing pedestrian desire lines to the connecting pathway network.The demolition of existing structures, and the erection of new structures over LRT tracks and 36th Street were critical considerations in the design.
Structural options were investigated to minimize construction operations over live traffic, and also reduce the number of temporary lane closures or shutdowns of the LRT system.
