Subject: 2013 Consulting Engineer’s Annual Report

Dear Ms. Lafleur:

AECOM, an independent consulting engineering firm, is pleased to submit its 2013 Annual Report of the Illinois Tollway System. This report summarizes our findings with respect to the maintenance and operation of the Illinois Tollway system during the 2013 calendar year. The Report provides an overview of the physical condition of the system, significant accomplishments of the Illinois Tollway’s Capital Programs during 2013, anticipated major undertakings planned for Year 10 (2014) of the Congestion- Relief Program, anticipated major undertakings planned for Year 3 (2014) of the Move Illinois Program and general insurance and Renewal and Replacement deposit information.

Capital Program projects for 2013 and the Illinois Tollway’s continuing preventive maintenance program have contributed to the preservation of the system, as required by the Amended and Restated Trust Indenture effective March 31, 1999. Most notable was the completion of the reconstruction and widening of the eastbound Jane Addams Memorial Tollway (I-90) from west of the Kishwaukee River to west of Elgin Plaza 9; rehabilitation and widening of the Elgin-O’Hare corridor from Roselle Road to Meacham Road; Jane Addams Memorial Tollway (I-90) & Illinois Route 47 Interchange reconstruction; systemwide intermittent pavement and bridge repairs as required; systemwide pavement marking as required; the ramp improvement program; systemwide bridge and structural wall repairs as required; and systemwide Intelligent Transportation Systems expansion. The Capital Programs will continue to address the pavement, bridges, overhead sign structures, and structural walls recommended for major rehabilitation, reconstruction or repair in the next six years.

We appreciate the cooperation and assistance provided by the Illinois Tollway staff during the course of our annual services.

Sincerely,

AECOM

In addition, it is anticipated that the Tollway will have increased the systemwide lane mileage by approximately 35% at the conclusion of the current Capital Programs. This will have been accomplished through various widening projects, construction of route extensions and new interchanges, and the inclusion of the Elgin-O’Hare corridor.

Exhibit 1 illustrates and Appendix A lists the approved Capital Program projects completed or proposed by the Tollway.

Congestion-Relief Program – Open Roads for a Faster Future In September 2004, the Tollway Board of Directors approved the CRP to address the existing infrastructure deterioration, congestion relief, the needs of growing communities, enhancement of local economies and cutting-edge initiatives. The CRP improvements have and will continue to provide safe, efficient, and convenient travel for the millions of motorists who travel the now 286-mile Tollway System.

The CRP includes five major goals which are:

FIX IT: Fix the existing infrastructure by 1 reconstructing and widening most of the roads systemwide; more than 90 percent will be rebuilt or rehabilitated. CONGESTION RELIEF: Reduce travel times by 2 converting the entire mainline system to open road tolling to allow I-PASS users to pay tolls electronically at highway speeds. MEET NEEDS OF GROWING COMMUNITIES: 3 Extend the Veterans Memorial Tollway (I-355) south to accommodate the needs of growing communities. ENHANCE LOCAL ECONOMIES: Establish corridor 4 planning councils to strengthen the partnership between the Tollway and the communities it serves. Improve mobility for communities served by the Tollway through a revamped interchange policy, intermodalism and context-sensitive improvements such as aesthetic enhancements, landscaping, noise walls and bicycle accommodations. CUTTING-EDGE INITIATIVES: Implement 5 Intelligent Transportation Systems technology and congestion pricing to better manage congestion and serve Tollway customers.

Most projects address more than one of these goals and are proposed on all routes of the Tollway System. The following are ILLINOIS TOLLWAY CONSULTING ENGINEER’S 2013 ANNUAL REPORT 13

The initial program for 2005 to 2014 was adopted in 2004. SAVE DRIVERS TIME AND MONEY: Congestion is expensive Since then, a comprehensive re-evaluation of the entire for residents, businesses and governments. By limiting our system and an extensive review of the condition of the ability to get around, it restricts people’s choices of where Tollway roadways and structures continue as part of the to live and work.

Progress since September 2007 has resulted in BUILD A 21ST CENTURY TRANSPORTATION SYSTEM: The the reduction in the overall CRP budget by management to Move Illinois Program will help to ensure that the region retains $6.1 billion. In November 2010, the CRP budget was further a competitive advantage over other major cities in the U.S. and reduced by approximately $300 million to $5.8 billion. This around the world through the reconstruction and widening of budget reduction was a result of actual project savings from existing routes and the construction of new route extensions completed or nearly completed projects and the elimination and interchanges with focus on all-electronic toll collection. of the design for the reconstruction and widening of the Jane Addams Memorial Tollway (I-90) from the Kennedy TAKE CARE OF THE EXISTING SYSTEM: The Move Illinois Expressway to Newburg Road. Program commits funds for the reconstruction of the remaining critical sections of the Tollway System not addressed as part of the CRP. Since the original construction of these critical sections, a combination of age, weather, use and heavy truckloads has deteriorated these roadways making reconstruction necessary to provide customers with safe and efficient travel.

BE THE “CLEANEST AND GREENEST” PROGRAM IN HISTORY: The Tollway’s “Building Green” efforts have proven that it is possible to minimize the environmental impact of new roadway construction by reducing, recycling and reusing materials.

Edens Spur (I-94) The 4.8-mile Edens Spur (I-94) was constructed in 94 1958 as part of the original pavement network and consisted of three lanes in each direction. An HMA overlay was added to this pavement in 1976 and was subsequently resurfaced in 1995. Rehabilitation of this section was completed in 2010 which included removal of the existing HMA overlay and the placement of a SMA overlay. As part of the Deerfield/Edens Spur improvement project, the west end pavement was reconstructed in 1997 and Plaza 24 (Edens Spur) was constructed in 1998. Plaza 24 (Edens Spur) was subsequently converted to ORT in 2006.

The majority of this pavement was rated in “good” to “fair” condition (CRS) with an RSL rating of 3 to 8 years. These ratings are primarily a result of the rehabilitation work completed in 2010 which has extended the RSL of this pavement however, as anticipated the CRS and RSL ratings have rapidly deteriorated to a point where the majority of the pavement is anticipated to require work within the next 3 to 8 years. Reconstruction of this route is programmed to occur in 2021 to 2022 as part of the Move Illinois Program. Intermittent repairs will likely be required in this area until this scheduled reconstruction.

Environmental Initiatives The Tollway is committed to protecting the environment and implementing numerous green initiatives throughout the Tollway system and construction projects. In general, recycling and waste reduction is utilized in most construction projects including recycling tires, shingles, or demolished asphalt surfaces in new HMA pavements or rubblized concrete in new base materials. The Tollway is also working with Argonne Laboratories to investigate various solar technologies’ effectiveness in the upper Midwest. As part of the Tollway’s 15-year Move Illinois program, design has begun to retrofit maintenance yards to achieve LEED status including better protection of stormwater and introducing Green Infrastructure Practices. 2013 environmental initiatives throughout the Tollway included both the continuation of previous commitments along with new Mitigation. The following is a summary:

Systemwide Wetland and Endangered Species Mitigation Coordination and Permitting The Tollway continued wetland and endangered species mitigation due to past impacts from the Veterans Memorial Tollway (I-355) South Extension completed in 2007. Required conservation measures were completed in previous years, however, monitoring and management of these sites is on- going due to regulatory requirements and commitments that the Tollway made to local partners. Specifically, these efforts included habitat creation and enhancement for the federal endangered species, Eastern Massasauga Rattlesnake and Hine’s Emerald Dragonfly, as well as continued vegetation management to ensure the success of previous efforts.

Habitat restoration efforts continued for the Eastern Massasauga Rattlesnake which included native prairie establishment on Cook County Forest Preserve (CCFP) lands with the goal of turning management responsibilities back to the CCFP in 2014. Also, the ongoing Hine’s Emerald Dragonfly research and joint efforts of habitat restoration in Cook, DuPage, and Will Counties will continue through 2014. This first of its kind endeavor, involves new rivulet creation (natural water features) for improved habitat, as well as genetic population research, captive rearing studies, and ongoing larval and adult dragonfly surveys. The study has generated valuable information on the status of population genetics and laboratory rearing, as well as increasing the population size due to the cage-raising of the larvae. Larvae will be released and this program will determine its future in 2014.

Systemwide Flooding Study Severe pavement flooding occurred along the Tri-State Tollway (I-294) between Cermak Road and 31st Street on the morning of July 24, 2010. The Consulting Engineer investigated the site and determined that all southbound mainline lanes and the southbound Cermak Road exit ramp were flooded with up to 2.5 feet of standing water. This situation was generally attributable to several factors, including the following:

O Stormwater runoff leaving the Tollway’s jurisdiction into a private drainage system which acted as a bottleneck. O The low pavement elevations along the Tri-State Tollway (I- 294) did not have an overflow route to Salt Creek for higher frequency storm events in case the drainage system was surcharged. O A detention basin stand-pipe control structure that was clogged by debris. O The dual 60-inch diameter culverts draining offsite runoff beneath the Tri-State Tollway (I-294) were restricted by the dual 60-inch diameter culverts beneath Cermak Road since one of these pipes was lined with a 30” diameter pipe. Drainage improvement work at these locations has been added to existing contracts and the Maintenance Division has Subsequent to this flood event, the Consulting Engineer begun to implement minor repairs to decrease the flooding conducted a survey of the entire Tollway roadway system for risk at these locations. locations with similar issues.

STRUCTURAL EVALUATION: The structural evaluation within this maintenance section indicated strong moduli values in each direction with good subgrade support. Overall, no voids were found and joint load transfer values were over 80 percent indicating no loss of support.

PAVEMENT SURFACE EVALUATION: The majority of pavement within this maintenance section is rated in “excellent” condition (CRS) with an RSL rating which widely varies from 9 to 20 years or more. North of the I-55 interchange, PCC repairs were completed with the overlay that was placed over most of the mainline pavement in 2010. The pavement on the collector-distributors and the pavement around the mainline plazas were overlaid in 2013. Widening and resurfacing was completed in 2009 for the pavement from Milepost 15.5 (75th Street) to Milepost 19.5 (Ogden Avenue). Reflective cracks have already been observed and will need to be monitored. C
