AIM’s Transportation Engineering & Design experience includes conceptual, preliminary, and final designs for interstate, state, county, and local roadways. Whether the task requires the design of interstate widening and associated urban interchanges, upgrading major urban and rural arterials, resurfacing or enhancement projects, AIM is experienced and ready to address all of its clients’ needs.

AIM led the design of the reconstruction of a two-lane ramp from WB SR 60 to NB I-75 with the addition of a new auxiliary lane for NB I-75 to the end of the project limits. The proposed I-75 auxiliary lane was accommodated by two independent bridges adjacent to Bridge Number 100471 over CSX Railroad and Bridge Number 100469 over Woodberry Road. Existing Bridges 100471 and 100469 were re-decked and the approach slabs were replaced as part of this project. Other improvements included drainage, permits, utilities, retaining walls, crash walls, noise analysis, ITS, signing, and pavement marking. The construction contract also included three additional “goes-with” interchange improvement projects for which AIM was the lead project.

AIM prepared the preliminary engineering and environmental (PD&E) analysis for the widening of Littleton Road from the Kismet Parkway / NE 24th Avenue intersection to the US 41 intersection in Lee County. This project included the evaluation of alternatives for the realignment of Littleton Road from the offset Kismet Parkway / NE 24th Avenue intersection to Yellow Fever Creek and improvements to the existing T-intersection with Corbett Road, which was in a 90-degree curve. At the completion of the PD&E study, AIM conducted the design of the first segment of the corridor from west of the NE 24th Avenue intersection to Yellow Fever Creek. The proposed multi-modal improvements included new construction of a four-lane urban, divided road with 11-foot travel lanes, four-foot bicycle lanes, sidewalks, and a multilane roundabout at Corbett Road. The stormwater management design included an enclosed drainage system with ponds out-falling to Yellow Fever Creek. Permitting efforts with SFWMD and USACE were expedited for an abbreviated schedule to reach construction in one year. AIM’s design, survey, and mapping teams also supported the County with right-of-way acquisition concurrent with design and utility coordination efforts including coordination meetings and utility work schedules for relocation of overhead distribution lines and poles and multiple underground communication utilities.

AIM, as the prime consultant and engineer of record, led the design of safety and operation improvements along US 441 through Leesburg. The design achieves these improvements by removing an existing two-way left turn lane and constructing a raised median from Griffin Road to Dr. Martin Luther King, Jr. Boulevard. The design accommodates left-turn access to side streets and properties at designated median openings along the corridor. The need for these improvements was identified by FDOT in an access management study completed in 2018. The new roadway cross section will continue to have three travel lanes in each direction and a raised median. AIM’s design also includes pavement resurfacing, sidewalk construction, mast arms for traffic signals, pedestrian crosswalk signals, median landscaping, new drainage structures, and lighting upgrades. The proposed improvements were presented at local agency meetings and a public hearing.
