Challenge

The Chicago Department of Aviation (CDA) tasked InNova’s project team with redesigning Taxiways E1, E2, and E3 at Midway International Airport to address Federal Aviation Administration (FAA) comments. All three taxiways connected directly to Runway 13L-31R, creating a three-taxiway entrance without safety islands. To meet FAA requirements, we were asked to evaluate options and develop a redesign that would transition the intersection into a two-taxiway entrance with the addition of islands.

Solution

Our team analyzed multiple design scenarios to achieve compliance while sustaining airport operations. We studied the geometry of taxiway centerlines, developed connections to existing pavement, and designed new taxiway fillets. Using AviPLAN, we simulated aircraft movements to validate operational efficiency and safety. In addition, we created a detailed phasing plan that enabled construction to proceed while maintaining peak operational capacity at the airport.

Outcome

In July 2024, the CDA implemented restriping and realignment of Taxiways E2 and E3, along with modifications to adjacent taxiways, following our design recommendations. The improvements resolved a challenging intersection, enhanced safety, and streamlined operations for more efficient aircraft movement at Midway International Airport.
