SR 249 Bridge Superstructure Replacement 6

Project Approach

Des #1600500 SR 249 Bridge over US 12, NICTD, NS and South Boundary Road

Bridge #(249)12-64-02673AThis two-lane, ten-span, continuous pre-stressed concrete bulb-T bridge located on SR 249 over US 12 and two railroads, in Porter County is a critical connection for international commerce and the local economy. The bridge provides a vital railroad grade separated access point to the Port of Indiana and Arcelor Mittal Steel.

Due to the heavy commercial aspect of the Port and Arcelor Steel, the commercial vehicle AADT is approximately 40%. Additionally, the bridge is within 15 miles of an Indiana Toll Road Exit and SR 249 is designated as an Extra Heavy Duty Truck Haul Route, therefore, the design vehicle for special Toll Road Loading and Michigan Train Truck will be must be utilized during design.

The SR 249 Bridge provides access to the Port of Indiana over US 12, NICTD, NS, and south boundary road. The mini-scope for Des #1600500 highlights the investigation of various beams exhibiting cracks in the top flange. The findings identified Delayed Ettringite Formation (DEF) due to improper curing of the beams at the time of construction in the casting yard as the root cause of the exhibited cracks. The mini-scope recommendation is the full replacement of the superstructure to remedy the issues affecting the beams.

The Lochner Team’s Approach is simple,

� Facilitate Meetings with the various stakeholders to develop a robust process for assessing a preferred alternative for the superstructure replacement of this critical structure

� Develop a Robust and In-Depth Engineer’s Report detailing the preferred alternative

� Prepare fully engineered structural plans for the preferred alternative

We know the importance of coordination and communication on a project of this level of complexity. Our team was specifically developed with personnel who have close working relationships with the various stakeholders within the project limits. Our team adds value to INDOT by complimenting INDOT’s project management processes with Lochner’s national structural design experience and keen project insights.

SR 249 Bridge Superstructure Replacement 7

Alternate 1SR 249 Superstructure Replacement (Two Lane Bridge)

The first Alternate is the replacement of the existing superstructure with new bearings, beams, approaches, deck and parapet wall with the same cross section. This alternate will review options for replacing the prestressing concrete beams with steel girders. A life cycle costing analysis will be completed to determine the life cycle maintenance costs for each beam type. Additional items to be reviewed include review of various deck construction systems and joint vs. jointless construction. Analysis of the existing conditions and an in-depth investigation of the structure will be critical to developing this alternate.

Des #1600500 SR 249 Bridge over US 12, NICTD, NS and South Boundary RoadThe LOCHNER Team has reviewed the Mini-scope for the SR 249 Bridge Superstructure replacement and identified two possible alternatives with various Maintenance of Traffic configurations. The final alternative and preferred MOT configuration will be fully devel-oped through a comprehensive Engineering Assessment of this superstructure replace-ment project.

Maintenance of Traffic

The main component in the development of the alternatives is the preferred maintenance of traffic. We have identified four potential MOT Configurations based on the existing layout and localized limitations.

� Full Closure with Detour

� Signalized Single Lane Closure

� Temporary Adjacent Structure

� Bridge Widening

Alternate 2

SR 249 Superstructure Replacement with Bridge Widening

Alternate 2 focuses on developing a concept plan for widening the existing structure to accommodate three lanes of traffic. This option constructs a new permanent single lane bridge adjacent to the existing SR 249 Bridge.

Like alternate 1, this alternate will follow the same fundamental steps of life cycle costing analysis, existing structural investigations, and in-depth analysis of the various bridge elements to be replaced/constructed.

SR 249 Bridge Superstructure Replacement 8

Signalized Single Lane ClosureThe Single Lane Closure with Signalized Phasing will require temporary shoring of the bridge, phased construction, and traffic analysis for the signalized phasing. This option will require more time than a full closure and will require extensive construction phasing (thereby increasing costs).

Segmental single lane bridge deck removal in phases to reduce possible traffic backups

Potential Temporary Shoring for Bridge Construction

Pros/Cons

• Maintain Traffic on Structure

• All Construction within existing limits

• Design and Construction of Tem-porary Shoring

• Multiple construction phases

• Increased disruption to traffic due to phasing

Full Closure with DetourThe full closure option will require a traffic detour. One option is to detour traffic to the west over the emergency at-grade railroad crossing. This option will require:

Pros/Cons

• Upgrade of the at-grade crossing with gates, signals, bells and lights

• Construction of queuing lanes for turning movements from US 12 to the detour route.

• Temporary Interconnected Traffic Signals

• Resurfacing of Detour Route

• Extensive Railroad Coordination

• Potential for Rail/Vehicle colli-sion

SR 249 Bridge Superstructure Replacement 9

Temporary Adjacent Structure The Construction of a Temporary Structure Adjacent to SR 249 as a Maintenance of Traffic configuration will allow for two way traffic during construction. Phase 1 will construct a temporary bridge to allow unrestricted flow throughout construction. Phase 2 will remove and reconstruct the existing bridge. Phase 3 will switch traffic back to the original alignment and remove the temporary bridge.

Pros/Cons

• Maintain Two Way Traffic through-out Construction

• Cost of Temporary Construction Improvements

• Multiple construction phases

• Railroad Coordination due to temp construction within RR ROW

Rendering of Three-Lane Superstructure Replacement with Widening

Bridge WideningWidening the bridge could also aid in the maintenance of traffic during construction, while building a structure that allows for future maintenance and increased movement of goods and services into the Port of Indiana. A possible permanent reversible third lane could be developed to better support the expansion and growth potential available within the Port’s Authority.

Pros/Cons

• Maintain Two Way Traffic throughout Construction

• Possible reversible third lane

• Improved access into Port

• Cost of bridge widening

• Extensive Railroad Coordination

• Multiple construction phases

Additional Design ConsiderationsAccelerated Bridge Construction (ABC) methods

To minimize impacts to traffic during bridge construction activities Lochner has developed concepts for accelerated bridge construction (ABC) methods, including the use of self-propelled modular transporters (SPMTs), slide-in-bridge construction (SIBC), and elevated drop-in (EDI) elements. Lochner has designed and used these systems throughout the country to accelerate complex bridge construction.

Lochner will continuously evaluate various bridge construction methods throughout the development process to determine the most cost effective solution for this location.

Team Demonstrated QualificationsUS 20 & SR 2 Interchange Design| Rolling Prairie, ININDOTUS 20 and SR 2 meet just east of Rolling Prairie, at the only signalized intersection between two four-lane divided highways in Indiana. Both routes carry high volumes of truck traffic, and the east–west corridor carries Michigan Train Trucks, just like the SR 249 Bridge. Lochner is the Lead Structures Engineer on the project design team. The Team of Lochner and Troyer Group has been able to use innovative design ideals for this location to provide an extremely cost effective design that meets the needs and improves overall safety.

Wilson Street Bridge over Fox River| Batavia, ILIDOTThe Wilson Street bridge over the Fox River in Batavia, IL was a three-span earth filled concrete spandrel bridge structure, similar to the SR 933 bridge over the St. Joseph River in South Bend. The new structure is a three-span post tensioned continuous concrete slab top bridge. The filled earth structure was cut in half longitudely for staged construction in order to maintain traffic.

ITRCC PUSH| I-80/90, Lake to Elkhart CountiesITRCCThis project is rehabilitating 73 miles of I-80/90 Indiana Toll Road between Portage, IN and Elkhart, IN. The PUSH project is the largest project the ITRCC has ever undertaken at $200M. The two-year project involves pavement rehabilitation, ITS equipment upgrades, interchange rehabilitations, and repairs (including deck replacements) to 53 structures within the project corridor

SR 55 Lardo Bridge Replacement| McCall, IDIdaho Transportation Department (ITD)This project was the first slide-in-bridge-construction (SIBC) for the ITD and the first design-build project for the State of Idaho. Lochner provided structural engineering and design services for this project. The project utilized accelerated bridge construction (ABC) methods to accelerate the bridge construction and open the bridge to traffic more quickly than traditional construction.

SR 249 Bridge Deck Overlay| Portage, ININDOTTroyer Group was selected on RFP #1301 Item 16, Multi-Des Bridge Rehabilitation Services, Bridge Replacement, Rehabilitation Or Repair. The SR 249 bridge deck overlay was part of this project. During development a traffic analysis was completed that showed single lane closure is possible, but should be limited in to less than the full length of the bridge to minimize queuing.

I-94/I-294 Mile Long Bridge| Chicago, ILIllinois State Toll Highway AuthorityLochner is the lead design firm in joint venture to determine a preferred replacement/rehabilitation alternative for Mile Long Bridge. The bridge is a dual structure, 54 span, 16 units, with a total length of 4,933 feet. The bridges carry the Tri-State Tollway over a Canadian National rail line with Amtrak and Metra use, the Illinois and Michigan Canal, two bike paths, the Chicago Ship and Sanitary Canal, the Metropolitan Water Reclamation District, the Des Plaines River, a BNSF rail yard, Santa Fe Drive, and the 75th Street interchange. Project will utilize gantry cranes during construction.

I-80 Road Reconstruction| Salt Lake County, UTUDOTThe project’s major elements included improvements to ramp and mainline geometry, pavement condition, medians, bridge structural integrity, noise mitigation, signalization, and aesthetics. To minimize impacts to interstate traffic during bridge replacement, Lochner developed concepts for accelerated bridge construction (ABC) methods, including the use of self-propelled modular transporters (SPMTs), slide-in-bridge construction (SIBC), and elevated drop-in (EDI) elements. In all, Lochner designed seven bridges, three of which were moved into position using SPMTs, launched out over the local road, and then lowered into place.
