Allen Road Reconstruction / Peoria, Illinois

We were retained by the Illinois Department of Transportation to undertake Phase I Study and Phase II Design of the reconstruction of the section of Allen Road from Townline Road to Alta Road in Peoria, Illinois.

The project consisted of 1.1 miles of pavement widening, realignment and reconstruction, five intersection reconstructions, a freeway interchange terminal, reconstruction and widening of a 5-lane plus a path freeway overpass, construction of a multi-use trail tunnel under the roadway, and realignment of a y-intersection to a t-intersection. A total of 4 Intersection Design Studies (IDS’s) were prepared and coordinated with IDOT as part of the Phase I Study that included preliminary design of 2 roundabouts.  Study also required Section 4(f) public land coordination due to the adjacent Rock Island Trail.  Maurer-Stutz also prepared the Bridge Condition Report, the TS&L and the complete structure plans for the widening to 5-lanes with a bike path of the structure carrying Allen Road over the IL Rte 6 Expressway.  The structural work also included the coordination and design of a box culvert tunnel beneath Allen Road for the Rock Island Trail State Park Crossing.  

New signals were designed at all of the intersections, along with a storm sewer system with detention whose needs were identified during the drainage study for the project.

Veterans Parkway (I-55 Business) over Interstate 74 / Bloomington, ILlinois

We were selected by the Illinois Department of Transportation to undertake Phase I Structural Study and Phase II Structural Design of the reconstruction of the interchange of Veterans Parkway (I-55 Business) and I-74 in Bloomington, Illinois.

The project consisted of the complete removal and replacement of four structures carrying Veterans Parkway (I-55 Business) over Interstate 74.  New bridges consist of a straight, three span, steel beam superstructure supported on piers and integral abutments skewed 30 degrees left forward relative to the alignment of the bridge.  

Maurer-Stutz prepared a complete Structure Geotechnical Report including coordination of a sub-surface site investigation with our sub-consultant.  Work also included foundation analysis and recommendations for abutments and piers and approach slab footings.  Type, Size, and Location drawings were prepared and also all structure plans and specifications.

Preliminary design services included analysis of existing roadway and ramp geometries for concurrence with new design criteria and also assisted District 5 designers in development of geometries for future widening of I-74 beneath Veteran’s Parkway.
