West 21st Street over I-465 Indianapolis
This ACEC Honor Award Winning project included the desing of an overpass bridge and street approaches for the Accelerate 465 project. The 21st Street Bridge is the first bridge in Indiana to utilize a prestressed concrete U-beam. This beam type has been previously used by DOTs in Florida, Texas, Colorado, and Washington. The Indiana U-beam details provided improvements from previous designs by utilizing draped strands instead of debonded strands to improve beam performance in shear, using steel internal diaphragms to reduce weight and simplify internal formwork, and provided inspection access inside the box. The advantages of the U-beam compared to other Indiana standard beams are reduced structure depth, improved aesthetics, and more efficient use of materials. The beam details were developed as typical prestressed concrete members that could be designed utilizing common prestressed concrete bridge design software. Approximately 0.4 mile of urban street reconstruction was included in the project. The roadway approaches consisted of a curb and gutter section with enclosed drainage and MSE walls to minimize right of way impacts. The construction cost for the project was $7,050,000.

Hendricks County Bridge 34 on CR 700 North over School Branch
The existing area is within the flood plain and the bridge and roadway approaches were designed to pass a ten year discharge through the bridge and allow bridge and roadway overtopping for more extreme flooding events. A variable depth three span continuous reinforced concrete slab bridge was the selected structure type. The shallow superstructure minimized the grade raise of the roadway approaches to allow for over the road flow for extreme flood events. This design concept provided significant savings in construction cost compared to the longer bridge and roadway approaches that would have been required to pass a hundred year flood through the structure. The construction cost for this project is $391,000. The three lowest bids were within 3%. This is an indication of the clarity of plans and specifications and that each of the three bidders had a high level of confidence in the documents when preparing their bids.

The project required 1300 feet of four lane divided roadway reconstruction to raise the profile grade and provide the required minimum vertical clearance over the railroad tracks. This project demonstrates SJCA’s ability to “design to cost”. Our original cost estimate prepared with the Bridge Inspection Report was $2,875,000. A low bid of $2,239,996.48 was received compared to the Engineer’s Estimate of $2,661,911.21. The final construction cost at project completion was $2,303,723.85. The final construction cost was within 3% of the bid value demonstrating the high quality of the final construction documents.
SR 2 over Cedar Creek in Lake County.
The design for this major bridge rehabilitation project was completed by SJCA in 2005. The structure is in the middle of a “Y” shaped intersection in downtown Lowell. SR 2 is along a horizontal curve through the south side of the structure and Washington Street is on a tangent through the north side of the structure. The structure is a single span @ 28’ perpendicular to the abutments having skews of 11ş left at SR 2 and 53ş 42’ left at Washington Street. The project included complete superstructure replacement. The tight constraints within the “Y’ shaped intersection would have typically been constructed in three or more phases. Cost and time savings were achieved by developing a scheme that provided temporary structure support details without the use of false work to reduce the area separating traffic from construction and provide for construction of the project in two phases. Two superstructure types were utilized to further reduce the construction period for each phase. The majority of the bridge consists of composite prestressed concrete box beams eliminating the need for false work. A pie shaped segment at the north side of the bridge is a reinforced concrete slab. New semi-fixed integral end diaphragms were fastened to the existing vertical abutment walls eliminating all expansion joints on the structure. This project had very complex geometry issues and required a structure layout sheet for specifying beam locations and curved coping offsets and a spot elevation sheet. This project also demonstrates SJCA’s experience in “designing to cost.” The cost estimate prepared for the Bridge Inspection Report indicated an anticipated construction cost of $810,000. SJCA’s cost estimate submitted with the tracings was $762,802.16 and a low bid of $754.639.44 was received on the project.
SR 55 and SR 26 over Big Pine Creek in Warren County.
The design for this project, completed in 2006, consisted of replacing the existing superstructure with a three span continuous composite prestressed concrete box beam superstructure. The project had several unique items compared to typical superstructure replacement. Big Pine Creek is considered an exceptional use stream and expansion joints and deck drains were eliminated from the structure to prevent bridge deck drainage from discharging directly into the stream. The new superstructure was also designed to require minimal reconstruction to the substructure units. Permitting requirements for construction of the project were more involved than normal due to the exception use designation. A sag vertical curve immediately north of the bridge was re-designed to meet sight distance criteria. A review of the intersection sight distance at the SR 26 and SR 55 intersection north of the bridge was also performed. This project demonstrates SJCA’s ability to “design to cost”. Our original cost estimate prepared with the Bridge Inspection Report was $580,000. A low bid of $599,951.44 was received compared to the Engineer’s Estimate of $626,751.97. The final construction cost at project completion was $588,807.09.

CR 400 North over I-69 in Steuben County.
The design for this major bridge rehabilitation project in Fort Wayne District was completed by SJCA in 2004. The structure was converted from an existing 4 span bridge to 2 spans of 116’-6” and 117’-9”. The structure is built on a tangent and is square. The design included widening to provide a bicycle pathway and complete superstructure replacement with continuous composite steel plate girders. The bridge is located on a dead end road and closing the bridge was not an option since the route served as the only access for a residential area. The maintenance of traffic and structure details provided for maintaining traffic over the structure at all times overcoming the tight constraints of the existing narrow bridge width and the change in profile grade without the necessity of temporary bridge widening. Utilizing the center portion of the existing hammerhead pier and widening the outsides to provide a solid stem pier contributed to maintaining one lane of traffic throughout the project by eliminating the need for major excavation and pile driving near the construction joint.
Marion 1001F on 62nd Street over Guion Creek Indianpolis
This federally funded LPA project involved design of a superstructure replacement and widening for a single span bridge on West 62nd Street over Guion Creek in Indianapolis. The new superstructure is a single span spread prestressed concrete box beam. There were two street intersections reconstructed as part of the project. The roadway was widened to a three lane section. A pedestrian/bicycle facility was included on the south side of the bridge. The north shoulder width was increased beyond the minimum requirement to provide the required intersection sight distance at the Rodebaugh Road intersection. The Engineer’s Estimate was $1,256,555.00 and a low bid of $1,162,149.06 was received on the project. In addition to bridge rehabilitation design, this project demonstrates SJCA’s experience in intersection design and designing the bridge to accommodate intersection sight distance

Structure No. 031-49-4448B on US 31 over I-465 and Lick Creek in Marion County.
SJCA completed the design for this major bridge rehabilitation project in less than nine months. We started the design in July of 2008 and submitted the tracings in March of 2009. This accelerated schedule allowed INDOT to take advantage of the phase 1 economic recovery funds. The project consists of superstructure replacement for an existing seven span bridge. A new steel beam superstructure was selected in order to minimize the dead loads and utilize the existing substructure units. The structure also consists of three superstructure units to minimize forces exerted on the substructure units. This design concept also allowed for a different beam size and spacing for the middle three spans resulting in a significant decrease in the weight and cost of structural steel required. The expansion joints at the existing end bents were eliminated by providing semi-integral end bents. The caps and columns of the interior bents were also replaced. The existing bridge width was too narrow to maintain two lanes of traffic in each direction on this heavily traveled arterial. The traffic volume on the northbound lane is significantly higher than the southbound lane during the AM peak with the opposite condition during the PM peak. Movable barrier was utilized to maintain two lanes of traffic in the peak direction and avoid temporary over-widening of the bridge to maintain two lanes of traffic in each direction. This concept saved thousands of dollars by avoiding substructure widening. The construction cost of this project is $4,016,000.
I-69 over Lake George Road in Steuben County.
The design for this major bridge rehabilitation project in Fort Wayne District was completed by SJCA in 2004. The project included superstructure replacement and widening for twin three span bridges on I-69 over Lake George Road. A continuous steel beam superstructure was utilized to maintain the existing vertical alignment. This provided savings in the construction cost by minimizing the approach reconstruction which consisted of approach slab replacement and HMA wedges. The structure widening was relatively small and savings were achieved by reconstructing interior piers with longer cantilevers to accommodate the new superstructure width. The end bents were widened without driving additional piling by providing an increase in the cap overhang. The construction cost for this project was $2,400,000.
US 41 over K. B. & S. Railroad and E.B. US 52 in Benton Co.
