Currently, the City of Edmonton's public transportation system in Edmonton, Canada is being expanded by the addition of a new line – the Valley Line. The first stage, a 13.1 km long section, includes besides other feature a 400 m long twin tube tunnel, which southern portal was secured by an AT–Pipe Umbrella System with threaded nipple couplings.
