TransLink says SkyTrain service on the Expo and Millennium lines downtown should return to normal by about 7 p.m. PT Tueday.

A medical emergency at the Burrard Street SkyTrain Station played havoc with the afternoon rush hour commute.

SkyTrain service was slow for most of the afternoon as westbound trains terminated service at the Stadium SkyTrain station. The Canada Line wasn't affected.

TransLink established a bus bridge and a shuttle train to connect Waterfront and Stadium stations and advised eastbound passengers to walk to Stadium Station, where possible.

During the service disruption, passengers encountered significant delays and lineups getting into and out of the downtown core.
