Transportation Market Projects
Innovate Mound
SUE Engineering Services NTH provided the design-build team with data on the existing subsurface utilities to design and build the Mound Road project - one of the most important corridors in Southeast Michigan. Innovate Mound is more than a reconstruction project. It is a re-envisioning of the corridor to include improvements to the roadway, pedestrian facilities, and smart technologies for emerging mobility features. This project will serve the long-term needs of local businesses and citizens alike. 
MDOT M-85 (Fort ST. & Shelby Street)
Subsurface Utility Services (SUE) / Geotechnical MDOT plans to modernize the existing traffic signals and make ADA sidewalk ramp improvements at the intersections of M-85 and each of 3rd Street and Shelby Street in Downtown Detroit. The intersections are located in the heart of the Central Business District and serve both local and through traffic as well as pedestrians going to and from their work and various entertainment venues. The modernization of the traffic signals will provide safer and more efficient travel for the motorized, non-motorized, and pedestrian traffic. NTH is providing SUE services in support of the project. 
City of Warren Streets, Sidewalks & Water Mains
Structural Investigation Our long-term history with the City of Warren, and the mutual level of trust we have developed, allowed us to implement a program to provide full time construction observation services for critical operations and less than full time for operations for project demands having less potential risk, thus saving the overall costs to the City. NTH maintained open channels of communication with the City to head off construction related issues and to offer timely solutions to keep projects on track. Our experience and quick turn-around for unexpected conditions has reduced contractor claims for lost time. |
Gordie Howe International Bridge
Geotechnical Engineering This design build project is being constructed by the Bridging North America (BNA) team for the Windsor Detroit Building Authority. NTH has been involved since the early concepts of the project. Now, as Engineer of Record for geotechnical aspects, NTH is providing construction phase services to ensure that the project is constructed as designed and meets WDBA’s requirements and expectations. 
Wayne County Bridges and Rehabilitation
Geotechnical Investigations & Foundation Analysis And Design Wayne County is going through a major program to upgrade and / or replace aging existing bridges to meet bridge safety requirements. NTH has worked as a subconsultant to Michael Baker International to evaluate subsurface conditions at the locations of the referenced bridges. For each of these projects, prior to moving into final design, a well planned and executed geotechnical investigation was required to determine the prevailing ground conditions and evaluate requirements for replacement bridge elements and approach pavement sections. NTH provided recommendations consistent with Michael Baker's design methodologies. 
City of Detroit Streets (Asbury Park Road)
Roadway Rehabilitation In 2018, NTH provided geotechnical investigation and related engineering evaluations for Asbury Park Road. The investigation was performed for an approximately ½ mile stretch of the road between Warren Avenue and Paul Street where severe distress was noted by the City. The scope included providing recommendations related to the roadway rehabilitation, preparation of cost estimates for the various roadway rehabilitation options, as well as other design and construction recommendations for which three rehabilitation options were presented to the City. |
