Download the Purpose and Need (PDF, 18.1KB)

The primary need for this project is to increase capacity and improve traffic operations on I-95 and at the Cypress Creek Road/I-95 and (SR 870) Commercial Boulevard/I-95 interchanges. The project is also intended to improve safety within the vicinity, including access to I-95 and the arterial intersections. Secondary considerations for the purpose and need of this project include system linkage, modal interrelationships, transportation demand, social demands and economic development, and evacuation.

I-95 within the project limits currently operates at Level of Service (LOS) F. Additionally, SR 870/Commercial Boulevard operates at LOS E east of I-95 and LOS F west of I-95, while Cypress Creek Road operates at LOS E on both sides of I-95. Without improvements, the driving conditions will continue to deteriorate well below acceptable LOS standards. The I-95 Express Phase 3 improvements will help maintain or slightly improve the I-95 corridor LOS by adding one travel lane in each direction in the form of an Express Lane. The improvements proposed as part of this project will complement the I-95 Express Lanes improvements. The existing Cypress Creek Park and Ride southbound on ramp and SR 870/Commercial Boulevard southbound on ramp provide less than 500 feet of merge distance before the acceleration lane drops and merges with the general purpose traffic. This forces commuters to merge with the general purpose traffic while accelerating, which is an unsafe maneuver.
