The Bloomingdale Trail, part of “The 606,” consists of 2.7 miles of previously unused elevated rail line converted into a multi-use pathway connecting five parks and four neighborhoods on the northwest side of Chicago.

The Bloomingdale Trail was originally an elevated rail freight line along Bloomingdale Avenue. Once rail traffic slowed in the 1990’s community collaboration turned the attention of the City into creating a desperately needed greenspace. The project consisted of the creation of an elevated park and trail involving fabrication and erection of ADA accessible ramps every quarter of a mile in an effort to improve access to all citizens. Rehabilitation of viaducts and retaining walls was performed to increase safety and infrastructure longevity. The work included removal, transportation, and re-erection of the Ashland Ave. bridge to Western Ave. Other bridge work included structural steel fabrication and erection. Such as Milwaukee Avenue, which was previously a four span simple structure which is now a single span tied arch bridge allowing for the removal of all piers increasing the safety of the motoring public along Milwaukee Avenue. Additionally, rehabilitation and modification of more than 30 existing concrete viaduct structures involved the removal and containment of lead paint, structural repair of concrete, and in many cases replacement of substructure while the superstructure remained in place. Drainage improvements were performed within the footprint of the path to reduce the impact on city infrastructure. Grinding and resurfacing of Bloomingdale Avenue as well as reconstructing sidewalks to ADA compliance. Electrical work consisted of lighting along the pathway as well as viaduct lighting. Architectural landscaping along the length of the elevated trail included five parks and four sections of unique botanical features.


joliet moveable bridges

will county, illinois

Gonzalez was selected to provided construction inspection services for the improvement of movable bridges in the Joliet area and the bridge office building.  This work includes architectural, mechanical, and electrical improvements, along with installation of communications to remotely operate six movable bridges from the newly renovated IDOT Bridge office near the Jackson Street Bridge. The bridges are located at Jackson Street, Cass Street, Jefferson Street, Ruby Street, Brandon Road, and McDonough Street; all of which run over the Des Plaines River. 

Renovations for the two story bridge office included improvements to the architectural, mechanical, and electrical infrastructure.  The building's exterior work included improvements to the existing brick façade, new roofing, improved fire escape, and new windows and doors and special consideration for containment and disposal of lead contaminated paint on the fire escape. The interior was renovated adding three control stations for remote operation of the movable bridges. Mechanical improvements included new HVAC and plumbing.  Electrical work included outfitting the building with upgraded lighting, receptacles, a backup generator to ensure a reliable power source, and a SCADA system for remote operation.


Route 15 over IL 13

st. clair county, ILlinois

The Illinois Department of Transportation (IDOT) procured the services of Gonzalez to provide Phase III construction inspection services for the reconstruction of Illinois Route 15 over Illinois 13 and ICG Railroad in Belleville, Illinois.  The project was part of IDOT’s capital improvement plan that rated these bridges for replacement.  Illinois Route 15 is a highly travelled roadway located in an expanding community.  The roadway project was being built in two stages, one direction at a time, to minimize the impact to the traveling public.  The complete removal and replacement of these structures was complicated by the fact that both structures, and the construction site in general, is located next to wetlands.  Construction for the project had limited space to negotiate reconstruction of the structures and the associated roadwork.

This improvement consisted of removal and replacement of four bridge structures, box culvert installations, drainage improvements, earth excavation, fill placement, modified structural earth (MSE) walls, concrete pavement, asphalt pavement, signing, striping, and pavement reflectors.
