Repaving following a water main break repair at Speedway and Craycroft was expected to disrupt traffic at the intersection for much of Wednesday.
According to Tucson Water spokesman Fernando Molina, the break happened during construction in the 1 a.m. hour.
The 12-inch line was repaired within hours, but asphalt repairs were expected to restrict traffic at the intersection until 6 p.m.
Westbound Speedway approaching Craycroft was down to one lane. No left turns were allowed on eastbound Speedway and southbound Craycroft. Northbound Craycroft was closed at Speedway.
