The I-10 Managed Lanes Project would construct managed lanes within the center median of I-10, while maintaining the existing main lanes as general-purpose lanes. The additional pavement width necessary to accommodate the proposed managed lanes would be constructed by adding pavement in the median, and in some areas, widening along the outside edges as well, which would require pavement restriping. All improvements were proposed within the existing right-of-way (ROW).
As part of the NEPA Categorical Exclusion (CE) that was prepared for the proposed project, PCI also compiled and maintained an Administrative Record for the project. The Administrative Record included all documents and materials that were directly or indirectly considered in preparation of the CE, including but not limited to, policies, guidelines, directives, manuals, articles, technical reports, meeting minutes, memorandums, etc. All documents were organized in chronological order and were included in an index.
