143rd Street Reconstruction

from will-Cook road to Bell Road, Will County

CLIENT: Counties


OMEGA provided construction engineering services for the Will County Division of Transportation. The project consisted of full depth asphalt pavement reconstruction and widening, pavement resurfacing, storm sewer, detention basins, curb and gutter, traffic signal modernization and landscaping.

The existing 143rd Street two lane pavement was removed and replaced with a 64’ wide, 13¼” bituminous pavement to provide a four lane roadway with left turn lanes. Several areas of subgrade exhibiting poor soil conditions needed to be undercut and filled with porous granular embankment to provide a stable road bed. The existing Will-Cook Road pavement was milled to various depths to provide a smoother profile and resurfaced with 2” of bituminous surface course. New 30” to 72” storm sewer was provided for the entire length of the project together with related drainage structures. Two detention basins with a total area of 4.2 acres were constructed.

New traffic signals with emergency vehicle detection systems were installed at the intersection. The project was constructed in four stages while maintaining one lane of traffic in each direction.
