Significant progress was made for the retaining wall at Buffalo Creek. The wall was excavated to the bottom footing grade. Panels were placed and the wall was constructed back above creek level. A portion of the 78” storm sewer pipe at the creek was also replaced during this work effort. Storm sewer crews continued work south of West Cuba Road and north of Boschome Drive. Other work performed last week included removing the steel sheets for the temporary retaining wall north of Greenwood Drive and framing for the top of the wall anchor slab at the wall south of Illinois Route 22 began. Little progress was made last week on earth excavation and roadway embankment placement due to the ongoing rainy weather. Work will continue this week on storm sewer installation, retaining wall construction, and earthwork activities pending weather.

This past week earth excavation and roadway embankment placement continued. The embankment placement included filling the deep excavations at the ground improvement areas between East and West Cuba Roads and north of Greenwood Drive. Work this past week also included the continuation of precast concrete panel installation at the retaining wall south of Illinois Route 22 and the excavation for a retaining wall at Buffalo Creek. Storm sewer crews continue to work north of Boschome Drive and south of Illinois Route 22. This work will be ongoing for the next few weeks. Please note storm sewer crossing under Boschome Drive is anticipated to be installed mid-week. Traffic will be allowed to access Boschome Drive at all times but it may be reduced to one lane during working hours. Please watch for flaggers.

Drier weather this past week allowed large-scale earth excavation and roadway embankment to take place. Material is being excavated from high areas, then placed and compacted in lower areas. The profile of the road will be changed slightly. In general, high points will be lowered and low points will be raised to provide a roadway with more gradual slopes. Storm sewer across from Bristol Trail is nearly complete. This week the crews will move to north of Boschome Drive and south of Illinois Route 22. Concrete leveling pads were poured for the retaining wall south of Illinois Route 22. This allowed the contractor to begin installing the precast panels. Metal straps connected to the panels are compacted within lifts of aggregate. The aggregate is then tested to assure density requirements are achieved. Excavation for a retaining wall at Buffalo Creek will resume this week and level pads are anticipated to be poured near the end of the week. Please check the Photos tab for more in-depth information regarding the project.
Last week storm sewer installation continued across from Bristol Trail and will be complete in the next couple of days. A second crew will start this week north of East Cuba Road. The two crews will work in tandem to complete the underground pipe installation from East Cuba Road to Greenwood Drive. New sanitary pipe is being installed in the same general area north of East Cuba Road. Work on the sanitary sewer will continue through the end of this week and be stopped until work in the ground improvement areas is complete. Rain over Memorial Day weekend and throughout last week prevented large scale earth excavation operations from moving forward. With a favorable forecast, these operations will resume this week. Work on the retaining wall south of Illinois Route 22 was also impacted. Concrete leveling pads for this wall are now planned to be poured this week. The pads serve as a base to place precast concrete wall panels on. Sheeting installation for the temporary sheet pile wall north and south of Buffalo Creek completed last week. Tie backs to help secure the wall are scheduled to be installed this week and will be followed by excavation of soils Read More
