PHOENIX - Phoenix Sky Harbor's Sky Train could soon be extended.

At its meeting last week, the Phoenix City Council approved a multimillion-dollar project that would extend 2.5 miles to the rental car center.

Phase 2 could also help reduce traffic off Sky Harbor Boulevard for travelers who are departing and arriving to the terminals.

This new phase of the Phoenix Sky Train is expected to start construction in early 2018 and scheduled to open in 2022.
