The Ohio Department Transportation awarded E.S. Wagner Co. two separate contracts to construct the Greenbelt Parkway connecting I-280 and the north end of Toledo to downtown Toledo. The initial Greenbelt Parkway project required the construction of 1.5 miles of four lane divided highway through an area of swamps and illegal industrial waste sites. This project was the first time that ODOT had awarded a major new construction project that included a major environmental remediation effort. The environmental remediation phase of the project included the removal and disposal of 215,000 tons of solid waste; 50,000 tons of solid waste stabilization; 100 tons of RCRA hazardous waste disposal; and 8,000 tons of TSCA PCB disposal. Upon completion of the environmental phase of the project, construction of the new roadway included 265,000 cubic yards of soil excavation and embankment; 415,000 tons of granular embankment and subbase aggregate; 43,000 LF of storm sewer/underdrain and 48,500 tons of asphalt paving.
To complete the Greenbelt Parkway corridor, ODOT awarded the second phase of the project to E.S. Wagner Co. to construct a new interchange with I-280 and tie-in the completed Phase I Greenbelt Parkway construction. This project required the construction of three major structures over I-280 which included 360,000 cubic yards of excavation and 215,000 cubic yards of soil embankment. Similar to the Phase I Greenbelt Parkway construction, Phase II posed its own unique set of environmental issue. Whereas the remediation in Phase I dealt with solid wastes, Phase II presented challenges to managing contaminated groundwater. The groundwater remediation effort included setting up an on-site activated carbon/ion exchange water treatment facility to mitigate the heavy metals and hydrocarbons in 4.2 million gallons of on-site impacted water.
Despite the significant environmental issues encountered during the construction of the Greenbelt Parkway, this over $49 million project was completed on time and now provides uninterrupted access via I-280 from the north end of Toledo to downtown Toledo.
