1. Colorado Street reconstruction

Work on the stretch of Colorado Street from Seventh to 10th streets began in November and shifted to the north side of the Eighth Street and Colorado intersection as of July 31. Eighth was reduced to one westbound lane west of Colorado to Lavaca Street, and Colorado was reduced to one southbound lane from Eighth to 10th. The lane closures allow for the installation of a new storm drain and water and wastewater lines, wider sidewalks, and curb and gutter fixes as well as street reconstruction. This phase of the project is expected to be complete in October. Work will move to the east side of Colorado starting in January.

2. Southeast Allandale water and wastewater improvements

Replacement of water and wastewater lines beneath 12 streets in the Allandale subdivision continues. The current phase of the project spans Finley Drive from Hancock Drive to West 49th 1/2 Street and West 49th 1/2 from Finley to Strass Drive. The project also entails street overlay, a street maintenance technique that applies about 2 inches of asphalt to the existing road surface. Crews are also installing water and wastewater mains, valves, service connections and manholes.
