The at grade track was proposed by Mayor Doug to save some cost on construction. But I'm not convinced that at grade construction is significantly cheaper than elevated. At least not enough cheaper to justify cutting into the Urban Forest.

Yeah Surrey's current mayor suggested it - he thinks they could have Skytrain on-ground through the ALR too.

They could just run the skytrain to Langley on the existing line, build the "L" line as Skytrain and just put a pair of Wyes right after the before Surrey Central to allow the trains to switch between lines. It would also allow the Skytrain to operate in a twin-L mode, where the Surrey Central-Newton and Surrey Central - Guildford lines operate with Surrey Central or Gateway as terminus.

Or even better - have the Fraser Hwy line and the L line independent of each other and have a 'connecting' station like Commercial - Broadway (it connects the Expo and Millennium lines in CoV).
