Windsor Road (Philo Road to Race Street) Plans

The city, with the help of a consultant, is currently working on short term and long term plans to reconstruct Windsor Road from Philo Road to Race Street.

As part of the short-term plans, work crews will be patching potholes continually on this section of Windsor Road to keep the road open to traffic until pavement can be permanently reconstructed.  Motorists are advised to proceed with caution while travelling on Windsor Road from Race Street to Philo Road due to deteriorating pavement conditions.  Rough road signage is currently in place.

Advisory speed limits, which dropped the speed limit from 40 miles per hour to 30 miles per hour, were in place from February 21, 2014 to June 18, 2014. Starting June 19, 2014 the regulatory speed limit was reduced temporarily to 30 miles per hour until the pavement is reconstructed. The Windsor Road pavement is suffering from a unique chemical reaction that is causing the pavement to degrade at a rapid rate.


Here are answers to some commonly asked questions about the Windsor Road pavement:

Q:  Why is this section of Windsor Road falling apart?

A unique chemical reaction is occurring in the Windsor Road concrete pavement that is causing the road to deteriorate faster than most roads of a similar age.

Q:  What is the chemical reaction that is occurring on Windsor Road?

The apparent chemical reaction is called alkali-silica reaction (ASR). It is a process in which the portland cement and the aggregate combine with moisture, causing the concrete to crack and disintegrate. When the pavement was constructed years ago, the materials used were not screened for high alkali content (i.e., cement) or silica reactivity (i.e., mainly sand) because this problem was largely unknown to occur in Illinois during that period of time. Today, these materials are screened so this type of reaction can be mitigated by using different mix combinations of cement and aggregates along with other materials such as fly ash.

Q:  Where else in central Illinois is ASR occurring?

ASR is not unique to Windsor Road since similar pavement distresses associated with ASR have been observed in the concrete pavement at the Washington Street and Vine Street intersection.

The City of Champaign is experiencing ASR associated pavement distress on some of its roads, as is the City of Bloomington.  Interstate 39 north of Bloomington is also showing premature pavement distress associated with ASR.

Q.  Why isn't the contractor or material supplier responsible for the repairs?

The industry warranty standard is typically one year.  Required material testing and proper pavement construction did occur at that time.

Q:  How old is the Windsor Road pavement?

The road is approximately 22 years old.  Construction of this section of the Windsor Road concrete pavement was completed in the fall of 1991.

Q:  Why doesn’t the city just repave the road?

Repaving Windsor Road is viewed as a short term solution (i.e., less than five year life) due to the deteriorated condition of the concrete slabs, especially the joints.

Q:  What is the City’s long term plan to fix the road?

The city has hired Hanson Professional Services, Inc. from Springfield, Illinois, with help from funds from the State of Illinois, as a consultant to perform the preliminary engineering for this section of Windsor Road.  A key component of the consultant’s work will be to define the anticipated construction costs for this section of Windsor Road, including pavement reconstruction or rehabilitation options. Approval will be sought from the Illinois Department of Transportation at the completion of the preliminary engineering study.

Below are Windsor Road long term plan milestone dates:

  • Preliminary Engineering: Completed Spring 2014

  • Final Engineering Plans: Completed Spring/Summer 2014

  • Project Bid Opening: July 18, 2014

  • Construction: Start Summer 2014, Finish end of 2015

The signalization of the Windsor Road and Race Street intersection, and pedestrian safety improvements at the Windsor Road and Vine Street intersection near Meadowbrook Park will occur during reconstruction of Windsor Road.

Q:  What is the City’s short term plan to fix the road?

The city will continue to fill potholes as they develop until the project is under construction in late Summer 2014. 

Q:  How will the long term fix be funded?

The city is to receive $3 million in state and federal money toward the reconstruction of Windsor Road.  The balance of the project costs (i.e., an estimated $3.6 million) will be funded by issuing municipal bonds.
