The streetcar lines from Union Station to Colorado at Beckley are almost complete.

The $51-million Oak Cliff streetcar had been scheduled to open in March, but a delay in delivery of the cars is pushing the opening date to April.

Keith Manoy, the city’s assistant director of mobility, says the cars are expected to arrive in March. After that, they must be tested for several weeks. Once testing begins, the city and DART will have a better idea of when the streetcar could open, but for now, it’s looking like April.

An open house in February or March will inform the public of what to expect with streetcar service.

City Councilman Scott Griggs is pushing for an extension of the line, from Beckley to Zang at Seventh, to open as soon as December. But the Dallas Morning News reports that city management failed to extend a contract to Stacy and Witbeck/Carcon JV and HDR, which built the first phase of the streetcar line. And now no companies have bid to build the second phase, to Bishop Arts, nor the third phase, to the Omni hotel.
