Identified as a top priority during the development of the District’s Parks Master Plan, this portion of trail was the first phase of over two miles of planned trails to provide connectivity and recreation for District residents.
EHRA assisted with the district creation of Montgomery County Municipal Utility District No. 126 to accommodate a ±329 acre master planned community located in northern Montgomery County in the City of Conroe, south of League Line Road, west of Longmire Road, and adjacent to Lake Conroe.
EHRA completed preliminary engineering, phase one environmental site assessment and schematic development for the widening of Northpark Dr. between US 59 and Woodland Hills Dr. EHRA also provided program management, drainage analysis and design, traffic engineering, environmental documentation and schematic design for the roadway, as well as grade separation at the Loop 494/UPRR railroad crossing.
EHRA conducted traffic operations and access management studies for the Northpark Dr. corridor. This corridor is approximately 2.2 miles long and has major signalized and unsignalized intersections and driveways that access various subdivisions and industrial developments. These studies laid the groundwork for the widening of Northpark Dr. from a four-lane boulevard cross-section to a six-lane boulevard complete street. The new street design includes low impact development drainage, conventional drainage, a grade separation at the UPRR crossing with mechanically stabilized earth retaining walls, two at-grade crossings for bi-directional frontage access, reconstruction of two concrete bridges over a diversion channel, intersection improvements, a roadway-adjacent multiuse path and traffic signal improvements.
Drainage analysis and design included hydrologic and hydraulic studies of both existing and proposed conditions to demonstrate that proposed project components would not adversely affect the 100-year floodplain in the area. The roadway and traffic designs contained horizontal and vertical alignments, cross-sections, plan and profile, sidewalk and bicycle accommodations, intersection layouts, traffic control plans and signing and pavement markings.
As the program management firm, EHRA coordinated with TxDOT, UPRR, the City of Houston Council District E, COH Planning and Development Department, COH Public Works and Engineering Department, Montgomery County, Harris County, HCFCD and area residents throughout the project.
EHRA offered its Landscape Architectural services to complete a Parks and Trails Master Plan for the District.
Facilities requiring expansion were also common wall construction, and the EHRA team converted the facilities into aerobic digesters and sludge thickeners.
EHRA Engineering is proud to have partnered with the City of Sugar Land (COSL) to enhance the City's shared-use path (SUP) trail system, creating safer and more accessible pedestrian connections for the community. This project was an exciting opportunity for the team, contributing to the City's long-term vision for pedestrian-friendly spaces.
EHRA was contracted by the City for the design and implementation of four pedestrian bridges strategically placed to connect different sections of the trail system. These included three single-span bridges (90 feet, 100 feet and 150 feet) and one two-span bridge (130 feet and 100 feet) that cross the City's drainage channels. Each bridge was carefully designed to blend with the surrounding environment while providing a durable and safe passage for pedestrians.
A significant focus for this project was safe connectivity. One of the project's standout features is the innovative undercrossing integrated beneath an existing roadway. This addition allows pedestrians to continue along the trail system without having to navigate traffic, significantly improving safety and accessibility. To ensure a secure and user-friendly experience, the undercrossing was designed with retaining walls and strategic lighting and handrails to enhance visibility and usability.
Beyond bridge construction, EHRA also collaborated with COSL to seamlessly link various sections of the paved sidewalk network along drainage channels and roadways. These connections strengthen the continuity of the pedestrian infrastructure, making it easier for residents to navigate their community safely and efficiently.
This project mirrors EHRA’s mission in delivering high-quality, community-focused engineering solutions. Prioritizing safety, accessibility and sustainability, we are proud to have played a role in shaping Sugar Land’s growing trail system, fostering a more walkable and connected city for residents and visitors alike.
