I-88 Ronald Reagan Memorial Tollway Reconstruction, DuPage County, Illinois Chastain performed Phase III construction engineering services for a three year project for the Tollway. The project involved three separate contracts. Contract 1 involved reconstruction and widening of a two mile section of mainline roadway on I-88 between IL Rte. 83 and York Road. Work included the realignment of the northbound I-294 to westbound I-88 ramp via a new 936 foot long two-lane curved fly-over bridge; realignment of the Harger Road entrance ramp requiring over 100 feet of new retaining wall as well as a new PPC bulb T-beam bridge over Salt Creek; reconstruction of the Spring Road ramps and reconstruction of the IL Rte. 83 ramps. Construction cost was $55 million. Contract 2 involved the reconstruction and widening of IDOT's 22nd Street roadway under I-88 in Oak Brook from McDonald's Drive to Salt Creek bridge. Work included widening and realigning the roadway to three lanes in both directions including channelization for two left turn lanes and one right turn lane at Enterprise Dr. and Jorie Blvd. Project length was approximately half mile in length in a heavily populated, urban area. Project also involved a super structure replacement on the 22nd Street Bridge over Salt Creek; bike trail construction with parapet walls and bike railings; new traffic signals; extensive relocations of utilities via open trench and directional boring, including water main, sewer, electric, natural gas and fiber optics. Architectural elements such as ornamental festoon lighting and decorative finishes were also components of this project in this heavily travelled high profile area. Construction cost was $11 million. Contract 3 involved the new construction of a new sound barrier wall along approximately five miles of the south right of way of the I-88 corridor from IL Rte. 83 in Oak Brook to Finley Road in Downers Grove. The wall construction was soldier pile and architectural precast concrete panel. Construction cost was $10 million. All three contracts were completed in 2010. In the final evaluation from ISTHA they noted "... the CM worked very hard to resolve potential problematic issues before they became critical and was a big part of this complicated project finishing successfully and ahead of schedule." and HLC staff "...consistently outperformed expectations and helped ensure the successful completion of a difficult project." Chastain was awarded the 2010 ACEC-IL Special Achievement Award for our construction engineering efforts in this project. |
