About This Project
Helping to promote a mode shift in transportation, this pilot project provides a 4.0m wide shoulder bus lane as a transit priority measure (queue jumper) for authorized Trans-link buses during peak travel times on Highway 99 in Richmond. ISL was the lead design consultant, and provided detailed design and construction services. The work on this $9.1-million project included highway and drainage design; structural engineering; traffic engineering; geotechnical (Thurber), electrical (DMD), and environmental (Hatfield); preparation of cost estimates, tender documents, and record drawings; and engineering services during construction.
Project highlights include shoulder bus lane road widening over 7.7km, three new off-ramps, three modified on/off ramps, three abutment retaining walls, on-ramp advanced warning systems, traffic enforcement pull-outs, overhead guide sign structures and foundations, impact attenuators, drainage modifications and improvements, watermain relocations, and third party utility relocations including fibre optic lines.
ISL’s team worked with the Ministry to develop practical and cost effective solutions for the geotechnical work.
To maintain priority for buses within the site constraints, three off-ramps were replaced and three other on/off ramps modified. At these locations authorized buses share the on/off ramp with general purpose traffic as a transit priority measure.
