Project Description

The P-1 Englewood Flyover Project was designed as a key part of the CREATE initiative to ease rail congestion. A series of rail-to-rail and rail-to-highway grade separations, including a 2,100 linear foot flyover bridge, now elevate Rock Island METRA tracks over Amtrak and freight lines at 63rd and State Streets.

The series of grade separations approaching the flyover required bridge construction over 59th Street, 61st Street, 63rd Street, a Norfolk Southern overpass, the Dan Ryan (1-94) overpass, Wentworth Avenue, and 67th Street/Marquette Road.

Pile-supported cast-in-place concrete retaining walls were originally specified in multiple locations. Four of those walls were value-engineered using T-WALL to eliminate deep foundation improvements and accelerate construction. Additionally, railroad bridges previously at 60th and 66th Streets were removed and replaced with parallel T-WALL retaining walls. The space between the walls was filled, permanently closing the streets at those locations.

The consulting engineer, TranSystems, received the 2016 Hay Award for Excellence for the Englewood Project. The award was presented by the American Railway Engineering and Maintenance-of-Way Association (AREMA) on the criteria of “displaying innovation or improving safety or service performance reliability.”
