LA SALLE COUNTY - The Illinois Department of Transportation announced that weather permitting, work will begin on Interstate 39 in La Salle County on Monday, March 16. The work zone is the I-39 bridges crossing I-80 in La Salle.

Work will repair the I-39 bridge deck and will include shoulder repairs, replacement of expansion joints and the application of a latex overlay. There will be one lane closed in each direction throughout the project.

There will be work on I-80 to repair the shoulders and accommodate the work on I-39 above. Preliminary work will be done overnight from 8 p.m. to 6 a.m. and one lane will be open in each direction during this time and all lanes will open on I-80 the following morning. When the preliminary work is completed, two lanes of traffic in each direction will be maintained on I-80 during the entire $3.7 million project, which is expected to be completed in November.

Drivers are urged to pay close attention to changed conditions and signs in the work zone areas, obey the posted speed limits, refrain from using mobile devices and be alert for workers and equipment.
