191st Street Project


The Village of Tinley Park is extending 191st Street from Prosperi Drive to Oak Park Avenue, completing the road’s connection from Harlem Avenue to Oak Park Avenue. D Construction of Coal City, Ill. is performing the work, which began in August with earth removal. Work is expected to be completed by July 2018.

Once complete, 191st Street will have two lanes of through traffic and protected left-turn lanes from Harlem Avenue to just east of Oak Park Avenue. The intersection of Harlem Avenue and 191st Street will be improved with dual left-hand turns at all legs of the intersection, and an exclusive right-turn lane will be added to the south leg. A signal will also be added at the intersection of 191st Street and Oak Park Avenue, with an exclusive right turn lane on the east leg.

There are no detour routes associated with this improvement, and all public roads will remain open during construction.

The Illinois Department of Transportation bid the project on April 28, 2017, with D Construction as the lowest bidder at about $3.3 million. The Village secured federal and state funding to pay for the majority of the improvement and is responsible for approximately 17% of the total project cost.

Project Update (Aug. 6, 2018)
D Construction completed the surface course on 191st Street, and Precision Pavement Markings placed all of the thermoplastic pavement markings on 191st Street. Tri Tech installed the heavy duty hand holes and detector loops on Harlem Avenue. This week D Construction plans to place the remaining level binder and HMA Surface Course Mix E N70 on Harlem Avenue. The traffic signal turn-on for both Harlem and Oak Park avenues is scheduled for Aug. 14, 2018. The changeable message signs were installed on Aug. 2, 2018. The thermoplastic pavement markings on Harlem and Oak Park avenues will be placed in conjunction with the traffic signal turn-on.
