Following is a list of projects of similar scope with which Hurst-Rosche has been involved, including a brief description of each project. Client references for any particular project can be provided upon request.

Route FAS 942 over Cache River
Section 19BF2
Alexander/Pulaski Counties, IL

Hurst-Rosche Engineers completed phase I and Phase II work which included the preparation of the Bridge Condition, Hydraulic, Structure and Project Report and the preparation of the preliminary and final contract plans for the replacement/rehabilitation of two highway stream bridges for the construction of a new bridge over Cache River. Work included significant rough and finish grading and storm water design.

Route 189 over I-270 and C-D Roads
Montgomery County, MD

Feasibility studies, preliminary design and cost estimates, final design, specifications and shop drawing review were required for the construction of the bridge over I-270. It was a steel "flared" plat girder, composite, four-span continuous bridge. The measurements were 210 feet wide at the abutments and 105 feet at the center. The bridge contained an elevated urban diamond interchange (four ramps integral with bridge deck geometry) and utilized "hour-glass" framing providing challenging and innovative results in an unusual, but cost effective structure.

FA Route 304 (Illinois Route 143)
Madison County, IL

Hurst-Rosche provided detailed on-site inspection, TS&L development, boring location selection, foundation analysis, final detailed design, special provisions, estimate of cost, and consultation services during the construction of a retaining wall. The design included a variable height retaining wall with integral vehicular collision wall equaling 2,460 lineal feet including complex foundations, drilled shafts 30 to 48 inches in diameter and steel H-piles.

FA Route 2 (Illinois Route 3) over SPCSL Railroad
Madison County, IL

The scope of services included preliminary (TS&L) and final design, special provisions, estimate of cost, and shop drawing review for the redesign of a three-span curved W-beam bridge.

Risdon School Road over Doza Creek
St. Clair County, IL

This project was comprised of the replacement of Risdon School Road (TR 186) over Doza Creek and the reconstruction of approach roadway. Services included an environmental study, hydraulic report, survey work, right-of-way documents, Corps of Engineers permits, foundation borings, Department of Natural Resources permit, final plans, specifications and estimate of cost.

Walter Webb Bridge (North Road Bridge)
Hillsboro, IL

Three-span bridge was built in 1923 and has been in continuous service since that date. The proposed replacement structure will be a three-span PPC I-beam bridge, integral abutment configuration with double hammerhead piers adjacent to the streambed. The roadway will be realigned to allow construction of the new structure while maintaining traffic on the present bridge. Borrow for the project will come from an abandoned railroad embankment north of the site. Bridge approaches of 0.6 mile (rural section) and 0.15 mile (urban section including storm sewers) are included in the project limits.

Lake Hillsboro Spillway Bridge
Hillsboro, IL

Hurst-Rosche provided engineering services necessary to construct a replacement bridge over the spillway of Lake Hillsboro, including the east and west approach roadways to the replacement bridge. The bridge length was 100 feet and bridge width was 24 feet.

Route 43 Eastbound Roadway over I-695 Westbound Roadway
Baltimore County, MD

The project included feasibility studies, preliminary design and cost estimates, final design, specifications and shop drawing review for the steel curved plate girder, three-span continuous bridge.

FA 805 (Illinois Route 161) over Dutch Hollow Road, CSX Railroad, and Schoenberger Creek
St. Clair County, IL

The design services for this project included TS&L development (alternative bridge configurations and comparative estimates of cost), preliminary and final design, special provisions, and estimate of construction cost. The construction was dual four-span continuous, composite, welded plat girder bridges. Special seismic design incorporating seismic isolation bearings and special abutment design for negative skin friction loads was used in the construction of this project. Pier height was a maximum of 56 feet.

FA 9182 State Street over Alton & Southern Railroad
St. Clair County, IL

Hurst-Rosche provided the engineering services necessary to construct a four-lane, three-span, composite, steel beam bridge over multiple tracks to relieve a railroad-highway conflict situation. The project included the construction of 0.5 mile of approach roadway, seismic design-Category B, integral abutment, fixed pier configuration, and steel H pile foundation (46 meters). Services included TS&L development (alternative bridge configurations and comparative estimates of cost), preliminary and final design, special provisions, and estimate of construction cost for this project.

St. Louis Light Rail
St. Clair County, Illinois and St. Louis County, MO

Hurst-Rosche provided design services for the preliminary engineering phase of the St. Louis Light Rail project (MetroLink) over the Mississippi River, and Eads Bridge approaches in St. Clair County, Illinois and St. Louis County, Missouri. Technical Report No. 4 included a condition survey which described the in-depth inspection of the Eads Bridge including east approach structures (East St. Louis) and west approach structures (St. Louis), equaling 4,886 feet of rail deck. Conceptual and extensive preliminary design of replacement segments or repair/rehabilitation of existing approaches, spans, and piers including modifications and details and detailed a estimate of cost.

The project included (1) Eads Bridge east approach (1.875 feet of rail deck) including thru-plate girder spans and elevated stringer spans; (2) Eads Bridge three main spans, structural member replacement, structural repair and floor system modifications; (3) Eads Bridge east and west arcades; structural repairs and rehabilitation; (4) First Street railroad bridge reconstruction (thru-plate girder) twin single spans; (5) Second Street railroad bridge reconstruction (thru-plate girder) twin single spans; and (6) Reconstruction of Norfolk-Western railroad trestle over stream; prestressed/precast replacement deck, stage construction, widened structure to accommodate second track. The design loading was E-70 with diesel impact. The extensive, in-depth preliminary designs included member selection, item-by-item detailed estimates of cost for all structures, replacement elements, structure widening and structure modifications including substructure elements.

MetroLink Extension
St. Clair County, IL

Services included extending the light rail service within the Metro-East area from the present station in the City of East St. Louis to the location of the new Mid-America Airport (20 miles). This included extending the light rail system over (1) Southern Railroad, (2) Terminal Railroad, (3) Alton and Southern Railroad, (4) 71st Street, (5) 79th Street, (6) Tributary of Schoenberger Creek, (7) Silver Creek, and (8) Little Silver Creek. The project included facilities design, trackwork, maintenance and storage facilities, traction power, signals and communications. The trackwork runs along an abandoned CSX trackbed for a major portion of the project from East St. Louis to Swansea, turning north at Belleville Area College to I-161, then running along the I-64 corridor to the new Mid-America Airport.
