I-75 (SR 93) from east of SR 951 to SR 78 (Bayshore Drive) in Collier and Lee Counties is currently experiencing a high level of congestion. In response, the Florida Department of Transportation (FDOT) has initiated a planning study to evaluate the addition of express lanes in each direction of the interstate as well as analyze the corridor’s current and future capacity needs and develop a transportation program to implement necessary improvements. Lochner is leading development of the master plan study.

As part of the study, Lochner is analyzing and assessing the impact of widening I-75 on the social, economic, cultural, natural, and physical environment. From this data, Lochner will develop the location and design concept of the project in accordance with FDOT policy, procedures, and requirements. In addition to master plan development, Lochner’s efforts also include project management, public involvement support and oversight, key stakeholder/agency outreach, traffic network model development, safety analysis, conceptual mainline roadway design, Section 4(f) evaluation, and preliminary engineering report development. Future additional services include the preparation of PD&E studies, design-build procurement request for proposal packages, and support during acquisition of design-build contracts.
