Transportation Projects

I-465 and I-69 Interstate Rehabilitation Engineering ProjectLFA was assigned this project as part of an on-call design services contract with INDOT Central Office. This $3.3 million project – an interstate rehabilitation – consisted of added travel lanes, ramp widening and other modifications to two interchanges. Specifically, it involved added travel lanes to diverging ramp from SB I-69 from north of I-465 to north of 82nd Street Interchange. The project included approximately 12 lane miles and a railroad bridge widening to immedicately address chronic congestion problems and delay as part of a larger comprehensive solution.

I-69 at SR-37/116th Street Interchange Modification Engineering ProjectLFA was assigned this project as part of an on-call design services contract with INDOT Central Office. This $8.1 million project involved adding an inside median northbound travel lane to I-69 from the 82nd Street Interchange through the S.R. 37/116th Street Interchange. Interchange modifications were also developed for the S.R. 37/116th Street Interchange including added ramp and collector-distributor lanes. Ramp widths were increased to provide double left turning movements at each end of the overpass.

This was developed as a “fast track” project in less than six (6) months to meet INDOT’s immediate needs. The project provided approximately 9 added lane-miles fit within the existing right-of-way to address chronic congestion and delay problems along I-69 corridor through Fishers and within the 116th Street/S.R. 37 interchange specifically.

The interchange modifications were developed without any cost prohibitive additional right-of-way and consistent with the previously approved environmental documentation. Improving Level of Service at the interchange included adding double left turn lanes and signal modernizations for the 116th Street overpass as well as added lanes to each ramp approach to receive these movements. All overhead signage was updated and/or upgraded to address traffic changes, constructed modifications, higher reflectivity standards, and current MUTCD requirements. This project had two (2) Level One Design Exceptions that received INDOT’s endorsement and Federal Highway Administration approval.

Ireland Road at Locust Road Intersection BeforeLFA was selected by St. Joseph County for the signalization and grade improvements at the Ireland Road and Locust Road intersection. This project was a Hazard Elimination project (HES) with both vertical and intersection sight distance deficiencies. Further compounding this project difficulty was the proximity of two single family homes immediately north of the intersection and the needed 10 ft of cut to the existing profile. LFA proposed a context sensitive solution – whereby the existing homes remained – that relocated and reconfigured existing drives to allow garage usage with concrete modular block retaining walls to overcome the proposed elevation difference. This met the needs of each homeowner, while still meeting the project’s purpose and need.

Ireland Road at Locust Road Intersection Improvement After Engineering ProjectThe project was developed in 24 months as an INDOT LPA project from the notice to proceed to ready for contracts date. This included project design, soil investigation, right-of-way engineering, land acquisition, utility coordination and other development requirements. An additional project requirement was the residential septic field relocation in conflict with the proposed wall limits.

Key features:
– design development completed in 24 months from NTP to RFC
– construction costs within program amount – $1.2 million
– existing homes retained without additional relocation costs or impacts
– coordinated with adjacent INDOT bridge replacement projects
– context sensitive solution provided

Beyond the individual development requirements, this project also included coordination with two INDOT bridge replacements immediately north and east of this project’s limit. One ARRA bridge replacement was completed 8 months in advance and immediately north requiring adjustments to this project’s alignment and grade. The second bridge replacement was constructed immediately after this project requiring coordination addressing alignment, grade, drainage and maintenance of traffic.

LFA was solely responsible for roadway design, drainage design, pavement markings and signing, lighting, signalization, right-of-way engineering, maintenance of traffic, and construction inspection.

S.R. 49 Rehabilitation Improvements Engineering ProjectLFA was selected by the Indiana Department of Transportation to design the rehabilitation improvements on S.R. 49 in Porter County. The project was designed in conjunction with several INDOT Bridge Rehabilitation Projects inside and north of the project area. The bridge rehabilitation projects were designed by other consultants and coordination of design at project interfaces and maintenance of traffic plans were key to the project’s success. Originally designed as a pavement replacement project, INDOT re-scoped the project as a rehabilitation project to fit within available funding. The re-scoping resulted in major design changes and the project was delivered on the original design schedule. INDOT Drainage Design Standards had changed since the original construction; and, therefore, the entire project drainage was analyzed and modified to meet INDOT’s current standards. LFA was responsible for survey, roadway, drainage, signing, lighting, signal and pavement marking design.

U.S. 24 Over Tippecanoe River Road Replacement Engineering ProjectLFA was selected by the Indiana Department of Transportation to design the bridge replacement and additional road improvements on U.S. 24 in White County. Major features include designing a new 5-span, 478 ft. replacement bridge, realigning U.S. 24 toward the north to correct an existing east bank roadway curve, sidewalks, decorative street lighting and other pertinent intersection improvements.

Through Monticello U.S. 24 is the main connection across the Tippecanoe River. Part of the project’s requirements was ensuring that the project’s Maintenance of Traffic plan minimized impacts to both the City of Monticello and the significant over-the-road truck traffic on U.S. 24. This was accomplished by establishing a proposed work sequence that minimizes the impacts to the existing bridge through construction.

U.S. 24 Fort to Port Expressway Engineering ProjectLFA was selected to design a new partial control expressway with an at-grade intersection for the first constructed phase of Fort to Port. This project was the first of four constructed phases connecting I-469 to ODOT (Ohio Department of Transportation) constructed portion. This phase – as the first constructed – provided a key interim connection fulfilling Indiana’s commitment to Ohio to have it open to traffic by Fall 2009. This interim connection was made from existing U.S. 24 to newly constructed U.S. 24 via S.R. 101 while the other three phases were under development.

LFA was the design consultant selected for improvements to U.S. 6 in Portage and Porter Counties. This project is an Indiana Department of Transportation project with FHWA providing 80% of the construction funding and INDOT providing the 20% construction funding match to complete the project. INDOT provided design review and construction administration for FHWA to assure that all design conforms to INDOT and FHWA design standards. INDOT requested that the project be designed with Limited Access Right-of-Way to protect mobility throughout the corridor. INDOT has a policy of requiring all parallel utilities to be located outside the Limited Access Right-of-Way. While INDOT actually completed the Utility Coordination for the project, LFA redesigned the Right-of-Way and Limited Access Right-of-Way to provide a utility corridor behind the sidewalk that could be utilized by utilities as part of their relocation plans. Median islands were included for the portion of the project within the City of Portage city limits at their request. LFA coordinated a median island maintenance agreement with the City of Portage per INDOT’s request.

LFA also coordinated a sidewalk maintenance agreement, as required by INDOT for the Porter County portion of the project, prior to including sidewalk in Porter County project area. The project also included replacement and upgrades to six traffic signals, a new storm sewer system with two detention basins to mitigate stormwater impacts to an area with known stormwater problems. LFA was responsible for roadway design, traffic signal design, stormwater design, signing design, pavement markings, and right-of-way design.

INDOT selected LFA to design improvements on S.R. 17 in Plymouth and Marshall County. The project utilized Federal funds for construction with INDOT providing 20% and Federal Highway providing the remaining 80% to complete the construction. A center two-way left turn lane (TWLTL) was originally scoped for the project. Median island options were presented as an option to the TWLTL for a portion of the project. Resulting from the public hearing for the project, as requested by the City of Plymouth, median islands were incorporated into the project.

Project special provisions addressed construction sequencing to minimize impacts to the Marshall County Blueberry Festival held each year over the Labor Day weekend. This project was closely coordinated with a bridge rehabilitation project on U.S. 30 over S.R. 17 that LFA also designed. LFA was responsible for roadway design, traffic signal design, stormwater design and signing and pavement marking design.

The intersection of U.S. 20 and S.R. 9 is located in the City of LaGrange, LaGrange County. The intersection has historically accommodated a high traffic volume, including a large percentage of commercial vehicles on all approaches. Development in all quadrants contributed to limited intersection sight distance which when combined with the traffic and lack of auxiliary lanes adversely impacted the existing Level of Service for this intersection.

LFA was selected by INDOT to design the improvements, which included a new traffic signal, left turn lanes, storm sewer and improved Intersection Sight Distance. Due to the urban setting and limited available Right-of-Way, detailed attention was paid to all items affecting the footprint of the project, and every effort was made to minimize impacts. Additional Right-of-Way was ultimately required due to the added turn lanes, which resulted in the total take of one parcel and the addition of a modular block retaining wall to reduce the impact on another, allowing the property to remain commercially viable.

LFA was responsible for the roadway design, stormwater design, signal design, signing design, pavement marking, erosion control, maintenance of traffic and right of way design, and assisted with the Utility Coordination.

LFA was selected to design this intersection improvement project located in Marshall County. The project improved the geometry of this intersection so that the minor road approach would intersect U.S. 6, a rural arterial, at approximately 90 degrees. Previously, Plymouth-Goshen Trail intersected U.S. 6 in a curve, nearly on the tangent.

The minor road was realigned utilizing a superelevated curve to reduce project length and impacts to nearby properties. A majority of the existing intersection pavement was removed, some remained to be used as an access road and cul-de-sac for two residences and an electric substation. U.S. 6 also received improvements contributing to enhanced safety of the relocated intersection with the inclusion of a passing blister and the extension of existing guardrail. The roadside ditch was enclosed and routed underneath the cul-de-sac in order to minimize costly Right-of-Way acquisition that would have resulted in the relocation of the electric substation.

LFA was responsible for the roadway design, stormwater design, signing design, pavement marking, erosion control, maintenance of traffic and right of way design, and assisted with the Utility Coordination.

LFA designed this intersection improvement project in Elkhart County. State Road 19 between Elkhart and Nappanee lies on a Range line, and as a result has a series of offset intersections at the crossing County Roads. C.R. 30 is a higher volume road as it provides a more direct route to Goshen from S.R. 19, with fewer stop signs than other County Roads in the area.

LFA was responsible for the roadway design, stormwater design, signing design, pavement marking, erosion control, maintenance of traffic and right of way design, and assisted with the Utility Coordination.
