Sun Link officials will conduct high speed testing tonight on its final streetcar.
The agency will conduct testing from 11 p.m. to 5 a.m. on East University Boulevard between North Fourth Avenue and Euclid Avenue, according to Sun Link.
The south side of University will be closed between Fourth Avenue and Tyndall Avenue, and parking will not be allowed on that side of the street.
Residents with parking permits can move their vehicles to the closest side street.
Workers will also close streets and alleys that intersect with University in the area, although intermittent vehicle, pedestrian and bicycle access will be provided.
Police officers will help direct traffic and pedestrians during the testing.
