Project Description: Six locations along state routes within the city of Huntington were found to have sub-standard traffic signal equipment along with one location in Bluffton. Each intersection required new standard traffic signal equipment to be installed. Recent paving projects through the project intersections resulted in a desire to maintain the integrity of the new pavement. United suggested the use of wireless vehicular detection at each intersection within the city of Huntington to meet the client’s expectations. Through close coordination with a local Indiana supplier, United provided the wireless design, complete with interconnection between the intersections.

Project Description: The Indianapolis MPO, in partnership with the city of Westfield, commissioned United to analyze 193rd/191st Street from Eagletown Road to Moontown Road. This multi-discipline study required a holistic look at the 193rd/191st Street Corridor over a 20-year study period. The goal of the study was to assess the future traffic needs of the corridor segments and intersections and develop a programming schedule to provide guidance in planning for future improvements.

After reviewing available planning documents and traffic data, Heather was able to develop a multi-step plan for addressing current and future development along the corridor. This plan incorporated both traditional traffic volume growth through the use of a yearly growth rate, and the use of estimated future generated trips resulting from future development. Utilizing the future traffic data along each segment and at each intersection, Heather completed an operation analysis of each study intersection to determine the appropriate future improvements needed. Cost estimates were prepared for each recommended improvement and a schedule or program of future improvements was created to aid the City in planning enhancements along the corridor.

Project Description: Truly an all-encompassing signal project, the modernization of seven signals within the city of Elkhart required the replacement of standard signal equipment, the design of nearly 20 curb ramps, and pre-emption phasing with an adjacent railroad crossing.  Although existing signal poles were utilized in many locations, a thorough utility coordination process was required to facilitate the installation of pedestrian push buttons and eliminate overhead utility crossings within the limits of the span and catenary.  Heather used a unique approach at the intersection of SR 19 and Main Street, where a dual-arm cantilever signal structure reduced the total number of signal pole foundations at the intersection.  This method also allowed the signal service to be located in a more convenient location on the north side of the intersection.

Approximate Project Cost: $1.1 million

Project Description: The city of Anderson desires to upgrade the central traffic system and modernize all 99 city-owned signals. Heather’s team completed a scoping report to prioritize the modernization schedule for the signals and determine the appropriate central system for the City’s needs, while following FHWA guidance. Improvements include new signal heads and wiring, new traffic signal cabinets and controllers, vehicle detection, and pedestrian push buttons and pedestrian signal heads where required.

 
Existing curb ramps will be reconstructed where required to provide ADA-compliant access. The project will replace aging signal infrastructure originally installed in 1984. In addition, the newly installed signal system will allow City signal staff to remotely monitor and diagnose issues while improving the overall operation of the system.

Project Description: The added travel lanes project along SR 930 from Parnell Avenue to Crescent Avenue also resulted in the modification of four signalized intersections along the corridor.  The design speed of SR 930 required advance loop detection at the intersection of SR 930 & Anthony Blvd.; however, the close proximity of the bridge over the St. Joseph River required a more creative use of vehicle detection technologies.  To meet the client’s expectation of not altering the newly constructed bridge deck, Heather recommended the use of Microloop vehicle detection in the vicinity of the bridge.  The recommended detection technology allowed the required advance detection to be installed in advance of the signal while leaving the bridge deck untouched.

Project Description: This INDOT LPA project included the installation of a traffic signal and crosswalks at the intersection of Smith Valley Road and Woodman Boulevard. Right-of-way and budget constraints created a challenging design environment. The intersection is in a location of high pedestrian activity near Greenwood High School. The use of video detection replaced the traditional loop detection methods. Heather used a non-traditional strain pole configuration used in combination with the aforementioned detection system alleviated the need to acquire right-of-way and reduced project costs.

Project Description: The Design-Build Best Value contract to I-69 created an added travel lane in each direction to the median between State 37 Road (Exit 205) and State Road 38 (Exit 219) and a southbound lane along the shoulder between 116th Street and the new interchange at the 106th Street exit ramp.  The I-69 and Campus Parkway was converted from a traditional diamond to diverging diamond interchange.  The project widened and rehabilitated five twin bridges on I-69 and reconstructed three overpass bridges.

The state of Indiana and INDOT have a legacy of delivering Design-Build projects through a fixed scope and low bid procurement process.  The I-69 Major Moves 2020 built on this legacy and implemented the first Design-Build Best Value project procurement delivered by INDOT.  During this procurement, the project was broken into segments for evaluation which could be constructed for a fixed budget.  Additional value in the selection process was given to more completed segments.  The process allowed for elements of the scope to be changed if it was demonstrated the end product was as good or better than the original scope.

The budget established for the project was $85 million.  Additional value was recognized for being able to deliver extended length of added travel lanes to I-69.  IFA recognized the proposal delivered an extended design life for the pavement, rehabilitation of additional structures and added widening accomplished 18 percent more than was estimated within the $85 million budget.  The additional value was accomplished through:

  • The team developed efficiencies for Milestone Contractors through better maintenance of traffic which allowed for greater production.  The rehabilitation of the existing lanes was completed during nighttime lane closures.  Once rehabilitation was constructed, the widening for the added travel lanes was completed behind temporary concrete barriers separating traffic from construction.  The separation created increased safety for the traveling public and construction workers.  The increased construction production also resulted in the delivery of additional length of added travel lanes on I-69.  
  • The largest innovation was the pavement design which maximized keeping the existing pavement in place and the new widened pavement section.
  • The rehabilitated pavement minimized milling of recently surfaced pavement to only what was needed to create a continuous 2% cross slope.  It resulted in keeping more of the existing pavement and resulted in a 25% increase in pavement design life. 
  • The pavement widening consisted of a 14-inch HMA pavement section that exceeded the functional and structural performance thresholds.  When combined with the proposed rehabilitation strategy, the total tonnage of HMA required per linear foot is reduced from 6.41 Tons/lft to 5.03 Tons/lft, resulting in a 27% increase in the length of interstate that can be improved.
