Jane Addams I-90 Rebuilding and Widening Project

Owner: Illinois Tollway

As part of the 15-year, $14 billion capital improvement program, Move Illinois, the Illinois Tollway is rebuilding and widening the Jane Addams Memorial Tollway (I-90) as a 21st century, state-of-the-art corridor linking the Chicago Rockford International Airport to O'Hare International Airport. The $2.5 billion I-90 Rebuilding and Widening Project is increasing capacity, reducing delays and strengthening economic activity.

Originally built in the 1950s, the Jane Addams Memorial Tollway is part of Interstate 90, the longest interstate in the United States, and covers 77 miles extending from near the Wisconsin border to the Kennedy Expressway. The I-90 corridor from downtown Chicago to Rockford serves nearly one million travelers per day.

Lin Engineering, Ltd. established survey control for the entire I-90 project corridor from Randall Road (M.P. 52.10) to Kennedy Expressway (M.P. 78.65).

New I-70 Mississippi River Bridge & Corridor

Owner: Illinois Department of Transportation & Missouri Department of Transportation

The New I-70 Mississippi River Bridge, approach structures, interchanges and corridor connect Southwestern Illinois to downtown St. Louis, MO. The project was a monumental example of successful multi-state, agency, consultant, and stakeholder coordination with more than 30 entities working side-by-side to ensure the river bridge and its connecting interchanges were completed on time. With a main span of 1,500 feet — the third longest cable-stayed in the U.S. — the river bridge was designed in half the time of similar bridges. The team's design innovations transformed the previous, unattainable $1.6 billion design to an affordable, buildable design at $676.3 million.

The Missouri Approach spans consisted of a 9-span PPC NU-girder superstructure supported by multi-column piers with drilled shafts. The total bridge length is 1145' and the width varies from 86' to 146'. The horizontal alignment transitions from tangent to curved/tapered, and the bridge was designed for seismic category C. The Illinois Approach spans consisted of a 10-span steel plate girder superstructure supported by two-column piers with drilled shafts. The total bridge length is 2546' with an out to out width of 86'. The bridge is on a curved alignment, and the bridge was designed for seismic category D. The design was completed in 2009 and construction is complete. Lin Engineering personnel acted as part of a Design Team located in St. Louis, MO for the duration of the 12 month design project. The team performed design computations for the PPC girders, deck slab elevations and girder fillets, the seismic model and design loads, and all computations for the bearings and pier design. Lin Engineering's involvement on the Illinois Approach spans included the review of the seismic model results along with an independent review of the steel girder camber calculations.

West State Street in Rockford (US Business Route 20)

Owner: Illinois Department of Transportation

The West State Street corridor, originally marked U.S. Route 20, is an important trans-continental highway. The City of Rockford's goal is to revitalize the economic health of the central core of Rockford and the area along U.S. BR 20. This effort involved the re-emphasis of this route as a gateway into the community. Phase I design consisted of a five-lane limited access 4.0-mile section and realignment of a one-way. The existing flush median was removed and replaced with a divided highway with limited access. Land acquisition was required for the multi-use path to entice development and invite motorists through town.

Lin Engineering, Ltd. served as subconsultant for the project, and acted as lead designer for preparation of all drainage design elements, including preparation of the Location Drainage Report, and hydraulic reports. Stormwater detention was included in the design to account for the additional impervious area due to the roadway widening. Our firm also prepared the accident analysis, maintenance of traffic plans, and intersection design studies for the project.

IL 3 over the UPRR / Prairie DuPont Canal

Owner: Illinois Department of Transportation

The Illinois Department of Transportation required engineering services to prepare Phase I and Phase II design plans for the replacement of Illinois Route 3 over the Union Pacific Railroad (UPRR) and Prairie DuPont Canal in Dupo, IL. The existing structure, built in 1954, had significant damage which resulted in a sufficiency rating of 2.0 and therefore required replacing. Early coordination was required to ensure all affected parties were in agreement with the span configuration of the proposed bridge. The replacement structure is a four-span parabolically haunched plate girder bridge on drilled shaft foundations.

Lin Engineering, Ltd. provided structural engineering design support for the project, including the review of all shop drawings prepared during Phase III, and preparing loading computations and reviews for designs performed by others.

I-355 Rehabilitation - Butterfield Road to Army Trail Road

Owner: Illinois State Toll Highway Authority

Interstate 355 was originally constructed in 1989 as the North-South Tollway, to reduce travel times for commuters traveling north and south within DuPage County. Lin Engineering, Ltd. assisted in the preparation of roadway plans for the proposed rehabilitation in 2009 for the newly named I-355 Veterans Memorial Tollway from Butterfield Road to Army Trail Road. Work performed included preparation of Barrier Warrants Analysis and roadway plans to address all safety hazards within the project limits, including installation of new guardrail, anchors, and terminals to conform to AASHTO Guidelines and Illinois Tollway Criteria. Hazards identified and resolved within the project limits included unshielded bridge abutments within the roadway clear zone, unshielded and protruding sign structure foundations, substandard guardrail lengths, and regrading/flattening steep roadside slopes that inhibited vehicle recovery after road run-off.

IL 29 Phase I Engineering/Environmental Study

Owner: Illinois Department of Transportation

Lin Engineering, Ltd. was subconsultant to CH2MHILL for the IL Route 29 Engineering and Environmental Study, and provided hydraulic engineering services in connection with the Project Design Report, Environmental Assessment, Hydraulic Reports, and Location Drainage Study for Illinois Route 29 from north of Chillicothe in Peoria County, up to the I-180 interchange in Bureau County. The report involves the design of a four-lane expressway along proposed IL Route 29 on new alignment for a majority of the project limits. This evaluation included considerations for significant amounts of environmental, historical and cultural impacts, limiting the extent of proposed right of way available for purchase. The existing drainage patterns within this highly complex project area consist of a bluff to the west of IL Route 29, in several specific areas just abutting the existing roadway, in which significant cuts into the bluff were proposed, requiring extensive closed drainage systems. Drainage design constraints also included an existing railroad system just east of the mainline, and the Illinois River just east of the railroad. Historical overtopping of the roadway was prevalent in specific areas within the project limits. Main channel crossing with overflow structure at one stream crossing was modeled using multiple opening analysis feature. Impacts due to longitudinal floodway encroachments were analyzed for three separate locations, two involving encroachments to the Illinois River. Proposed roadway and drainage designs provided for significant considerations to existing drainage patterns and impacts, in addition to the environmental, historical, and cultural constraints within the project.

Wabash River Bridge

Owner: Illinois Department of Transportation

Lin Engineering, Ltd. was subconsultant to Alfred Benesch & Co. for the proposed replacement of the Wabash River Bridge project. The engineering services included the preparation of a scour analysis and report for the structure carrying FAP 827 over Wabash River in Wabash County, Illinois and Gibson County, Indiana. Lin Engineering computed scour depths for rainfall events up to the 500-yr event, and provided recommendations to the structural design staff for minimum depth requirements for the proposed piers and abutments for the replacement bridge. Scour computations were also performed to determine minimum depth requirements for cofferdams which were utilized in construction of these substructure elements. The existing bridge was to remain in place during the construction of the new bridge, and was a significant consideration in performing the scour computations for the project.
