Raney Street relocation and extension
The city of Effingham, Ill., selected Hanson to conduct a location study for the proposed extension of Raney Street from Wabash Avenue to Fayette Avenue. Raney Street was a two-lane, north-south road serving light industrial development in southwest Effingham. Fayette Avenue was a four-lane, east-west urban arterial connecting Interstate 57/70 to U.S. Route 40 and Illinois Route 33. This three-quarter-mile proposed improvement required a grade-separated crossing over the Consolidated Rail Corp.’s (CSX) facilities.
Hanson studied two alternatives for the extension location, taking into advisement projected heavy use of the road by large vehicles. After completing the location study, Hanson recommended a proposed alignment and profile and structure type. The final report also included an environmental class-of-action determination. In addition, Hanson provided technical testimony on behalf of the city at Illinois Commerce Commission hearings.
Hanson then designed a new structure to carry the proposed four-lane Raney Street extension over the CSX Railroad. The 362-foot-long multi-span superstructure featured a composite cast-in-place concrete deck on steel-plate girders and multicolumn piers with crash walls supported by drilled shafts. The abutments are both pile bent supported by steel HP piles. The approaches to the bridge include a mechanically stabilized earth wall system.
Hanson also designed a new pedestrian tunnel that passes beneath the superstructure. The 90-foot-long structure consists of three-sided precast-concrete segments supported on a cast-in-place concrete slab foundation.
During this project phase, Hanson provided the following: a geotechnical report; type, size and location drawings; field surveys; roadway plans; final bridge drawings; shop drawing review; specifications; and construction cost estimates. Hanson also provided surveying, plat preparation and land acquisition services, including technical testimony at Just Compensation Hearings.
