Miracle Mile drivers frazzled by recent weekend street closures along Wilshire Boulevard can breathe a sigh of relief—or just enjoy a detour-less drive.

As City News Service (via My News LA) reports, above-ground work on the future Wilshire/La Brea Purple Line station has come to an end six weeks ahead of schedule. The street closures, which started in June and were expected to last 22 weeks, were necessary for initial development of the subway station.

But Metro contractors have fully excavated the site and added concrete decking so that construction can continue underground.

The Wilshire/La Brea station is one of three stops under construction right now along the first phase of the Purple Line’s planned extension to Westwood. Once complete, the train—which currently ends its westward journey at Wilshire/Western—will take passengers as far as La Cienega. Eventually, the train will travel all the way to Westwood.

Work on the first phase of the Purple Line extension is expected to wrap up by 2022, with Metro aiming to open the extended route to passengers in 2023.
