photo Streetcar rails are in place across the Houston Street Viaduct and into North Oak Cliff. The rails now run from the bridge, up Zang to Colorado, where they make a right turn toward Beckley.

All 1.6 miles of rail are expected to be complete soon. Once the installation is complete, traffic interruptions at Zang/Colorado will lessen, according to this update from DART.

The streetcar will open about a year from now, in early 2015.
