DOWNTOWN LOS ANGELES – Various lane closures and other traffic controls will be in place this week as the Los Angeles County Metropolitan Transportation Authority continues its geotechnical testing along the two-mile Regional Connector route this week.

The agency is locating utilities and performing soil borings, and noise and vibration tests as part of an ongoing environmental analysis for the project.

The test samples and data collected will provide information on subsurface conditions, allowing engineers to determine optimal excavation and construction methodologies of the planned underground tunnel and three stations.

Part of the testing will include “Sonic Core Drilling,” which measures noise and vibration in relation to geotechnical conditions and existing infrastructure.

The planned locations of the testing activities are:

May 10, 2011: Second Street at Main Street, Olive and Spring streets; and Gen. Kosciuszko Way between Hope and Flower streets.

May 11, 2011: Second at Los Angeles, Spring, and Olive streets; Alameda between First and Temple streets; Gen. Kosciuszko Way between Hope and Flower streets.

May 12, 2011: Second at San Pedro, Spring and Olive streets, and Gen. Kosciuszko Way, between Hope and Flower streets.

May 13, 2011: Second at San Pedro Street and Central Avenue; Flower at Third, Fifth and Sixth Streets; and at Second and Olive streets.

The project’s final environmental impact report is expected to be adopted by the end of 2011, with the possible initiation of construction in 2013. The project will provide three new stations, serving approximately 90,000 transit passengers daily.
