The Point: Watch for construction activity of three new walls

As part of RCTC’s Interstate 15 Express Lanes project, crews will begin construction of three additional soundwalls along I-15, south of State Route 91, in late May or early June. The walls will be built with tan, split-face block and range in height from 14 feet to 16 feet.

The construction contractor plans to work on the three walls during daytime hours. The contractor may expand those hours to stay on schedule, if needed. Residents may hear noise from equipment, back-up alarms and other construction activity.

Soundwall locations are determined by state and federal criteria. Outside noise levels must be 67 decibels or higher, and the wall must reduce noise by at least five decibels. Residents also must vote to approve the soundwalls in their neighborhoods.

The first project soundwall is under construction along southbound I-15 between El Cerrito Road and Cajalco Road. The wall is expected to be completed shortly; crews have been placing soundwall blocks for the past several weeks.
