Hinsdale Area Construction Updates:

5/2/24 - As part of the Illinois Tollway’s reconstruction and widening of the Central Tri-State Tollway (I-294) construction activity may have an impact on residential areas adjacent to the Tollway. Work will be performed throughout the day, with overnight and weekend work scheduled as needed. 

Current and upcoming construction will include the following:

  • Removal of existing noisewalls between Ogden Avenue and the Hinsdale Oasis is scheduled to begin this week and continue through May. Temporary fencing was installed to limit sight and nuisances. Noisewalls will be replaced following completion of roadway reconstruction scheduled for 2025.  
  • Roadway construction activity in May will include concrete breaking operations during daytime hours. Residents may notice some increased noise.
  • Relocation of the 55th Street watermain is scheduled to begin mid-May. Local road closures along Harding Road may be needed to complete this work and will be coordinate with the Village of Hinsdale.

The Tollway has coordinated with the Village of Hinsdale throughout the design, planning and construction of this project to reduce the inconvenience this construction project has on local residents and businesses near the Tollway.
