Field studies and surveys scheduled for 91 Freeway project

May 30, 2017

Field studies and surveys will be conducted in Cerritos, Artesia, Norwalk and unincorporated Los Angeles County throughout the year as part of a project to improve and widen the westbound State Route 91 (SR-91).

The Los Angeles County Metropolitan Transportation Authority (Metro) and the California Department of Transportation (Caltrans) District 7 will conduct the field studies and surveys in the public right-of-way and in private properties (with proper advanced notification and permission to enter). Field studies and surveys may include surveys for noise monitoring, biological resources, cultural/historic resources, paleontological resources and field topographic surveys. The field surveys will occur during daytime hours Monday through Friday.

The freeway project aims to improve operations along westbound SR-91, between Shoemaker Avenue and the Interstate 605 interchange and at the I-605 northbound off-ramp to Alondra Boulevard. The project includes improvements to freeway entrance and exit ramps and operational improvements for the northbound I-605 at the Alondra Boulevard off-ramp. Additional improvements are also anticipated on the arterial streets in the vicinity of the freeway ramp intersections.
