Metro_B2R_Polk St_100pct_VOL1_26.09.11_Halfsize.pdf

This is a project design document for the Metro agency in California related to the Brighton to Roxford Double Track (B2RDT) Project, specifically addressing Grade Crossing Improvements at the Polk Street location. The project is part of a strategic initiative to improve network integration along the Antelope Valley Line corridor by implementing safety improvements at four at-grade crossings. The document appears to be Volume 1 of the project plans at 100 percent completion status, dated September 11, 2011, and presented at half-size format. The Polk Street at-grade crossing has been prioritized ahead of the remaining segments for pre-construction phase work, following the completion of Plans, Specifications, and Estimates (PS&E) for Segment 4A. The overall Brighton to Roxford project was strategically divided into four distinct segments to optimize delivery and construction scheduling.

The document provides technical specifications and design details necessary for the advancement of the at-grade crossing safety improvement work at the Polk Street location. As a project design document, it serves as the foundation for the pre-construction phase and subsequent construction contracting for this critical infrastructure safety initiative on the Antelope Valley Line corridor within the Los Angeles Metropolitan Transit Authority's service area.
