Water from a fire hydrant damaged by a hit-and-run flooded into a trench for a recycled water pipeline Monday afternoon, undermining a section of Grant Line Road between Lammers and Byron roads.
Construction crews have been working on the roadway as part of a project to deliver recycled water to city parks, sports fields, medians and other landscaped areas for irrigation. The major transmission lines run along Grant Line and Byron roads as they go from the wastewater treatment plant off Holly Drive north of the freeway to the section of Lammers Road south of 11th Street.
The problems Monday began shortly after 5 p.m. Water escaping from the damaged hydrant under high pressure began to collapse the trenches under the road, which caused a section of the eastbound lanes near the Gateway Crossing Apartments to buckle.
Eastbound traffic on Grant Line Road was stopped at Byron Road, and cars backed up at the intersection as Byron Road grew congested with the evening commute.
Crews working on the recycled water project nearby were soon able to place large steel plates over the exposed trenches, and the road was opened about an hour later. They were expected to add the trench and road repairs to their nightly construction work between 9 p.m. and 3 a.m.
For the next part of the recycled water project, Byron Road is closed completely between Lammers and Grant Line roads until Tuesday as crews work around the clock to bore a water line under the railroad tracks at the intersection of Byron and Grant Line. More details about the recycled water project and the road closures are available on the city website.
