Atkins’ designers help improve highway interchange at I-75 and SR 70 in Manatee County, Florida - June 8, 2012
Tampa, FL — Atkins, one of the world’s leading design and engineering consultancies, has begun the engineering and design work needed to reconstruct and expand the Interstate 75/State Road 70 interchange in the developing area of Manatee County, near the city of Bradenton, Florida.
The Atkins design calls for reconstructing several miles of I-75 at the SR 70 interchange, making sure the new interchange is expandable from an interim six-lane configuration to ten lanes at some time in the future. Atkins is overseeing the design of the interim configuration, which is comprised of three general-use lanes and one auxiliary lane in each direction, for a total distance of more than seven miles.
The project specifies several additional miles of interstate widening to create auxiliary lanes on I-75, as well as more than a mile of widening on SR 70. In addition, the project calls for extensive work on several I-75 bridges, including replacing the bridges over SR 70 (along with their entrance and exit ramps) and widening the Foley Creek and Braden River bridges.
Consultants competing for the engineering and design contract were invited to propose design alternatives that were different from the options recommended in the Interstate 75 Project Development and Environment (PD&E) Study that was completed in 2010. The Atkins team, led by project manager Kayleen Mueller, PE—an engineer and project leader with more than 15 years of experience—performed an extensive interchange analysis that examined the advantages and disadvantages of more than 20 possible alternative configurations.
Atkins’ winning interchange design is a single loop with a bypass lane—an innovative yet practical and cost-effective design that has the capability of extending the acceptable service level of the interchange beyond the year 2050.
“Atkins has a long history of designing successful projects in the Manatee County area,” noted Mueller, “and we’re delighted to be selected for this project as well. The impressive growth of Manatee County has resulted in greatly increased travel demand, and this project should ultimately result in a more efficient travel experience for users of the I-75/SR 70 interchange.”
