Theproject includes the replacement ofa two-span reinforced concrete underfill archstructureoriginally built in 1926 with a two-span bulb tee beambridge.Sincethe bridge sitsadjacent tothe growing community of New Palestine, inclusive of abusy high school andhome to residentsalready experiencing construction fatigue,the team evaluated Accelerated Bridge

Construction (ABC) strategies to minimize disruptions. The Indiana office collaborated closely with HNTB’s Minneapolis, MN office toassessthe feasibility of ABC methods, including Prefabricated Bridge Element Systems (PBES) and Slide-In Bridge Construction (SIBC). These approaches showed the potential to reduce roadway closure durations to as little as three weeks to 1.5 months. Although INDOTultimately selectedconventional construction, the cross-office collaborationhelped tostrengthen INDOT’s understanding of ABC methods and pave the way forpotential implementationonfutureprojects.

Additional project complexities have included vertical profile adjustments to eliminate an existing sag curve, mitigation measures for potential endangered mussels within Sugar Creek, coordination with adjacent residences and nearby historic properties,future corridor compatibility considerations,enhanced demolition considerations tied to the existing bridge type, implementation of a temporary causeway, and shallow artesian conditions encountered near the pier foundations. To address these challenges, the Indianapolis office also partnered with HNTB teams in Milwaukee,WIand Cincinnati, OH,demonstratinga truly collaborative, multi-office design effort.

NORTHEAST DIVISION: Haverhill-Methuen Bridge Replacement DesignBuild

HNTBis part of ajoint venture(JV)to provide design build(DB)services for the HaverhillMethuenbridgereplacementDBproject. HNTBisleadingthe design to deliver two proposed alternative technical concepts(ATCs)that reduce the project's environmental footprint, lower the highway profile significantly and shift it away from residential properties,and accelerate the construction schedule.This new project islocatedone milesouth ofthe recently completedI-495 Haverhillbridgereplacementdesignbuildcontract no.605306-103045,an award-winning project for which HNTB served as engineer of record.

The newproject will replace the existing bridges carrying I-495 over the Merrimack River, situated between the cities of Haverhill and Methuen, Massachusetts. The project will realign the southbound span, eliminating two in-river piers to minimize the structure’s environmental impact,and effectively address local community growth and transportation needs.In addition to bridge and highway design, HNTB’s scope of work includes environmental permitting, geotechnical and hydraulic evaluations, traffic management, utility coordination, public outreach support, and stormwater management.

TechnicalRisks

Whilevery similarto the northerly crossing completed a few years earlier, this Haverhill-Methuen project presented some unique challenges:

Vertical clearances over Route 110/113 required asignificant vertical roadwayprofile raise to I-495 that challenged efficient staging and traffic management.

High-tension transmission lines traversing over the south approach made that profileraiseeven more challenging for proposed abutment construction and deep foundation (pile) installations. Construction for proposed highway (northbound) alignments forced management of widened slope areas over gas and sewer lines and suspect subsurface materials (soft clays and silts).

HNTB developed alternate technical concepts (ATCs) for the Massachusetts Department of areas.Environmental permitting required extensive coordination with the Massachusetts

DIVISION PROJECT HIGHLIGHTS

WEST DIVISION: Lynnwood Link Extension Final Design and Construction Support

The Lynnwood Link Extension is an 8.5-mile expansion of Sound Transit’s Link Light Rail system, extending from Northgate Station in Seattle to the Lynnwood Transit Center. The project includes five new stations, three structured parking facilities, and a guideway alignment composed of approximately 50 percent aerial structures and 50 percent at-grade andretained-cut sections. Much of the corridor follows the constrained WSDOT I-5 right-of-way, driving complex structural design solutions.

HNTB, injointventure with Jacobs Engineering (H|J), delivered full design and construction support, with HNTB providing project management leadership across all engineering disciplines. The structural scope was central to project delivery, involving elevated guideways, long-span crossings,retainingsystems, and integration with existing infrastructure in a densely developed corridor.

Key structural challenges included: Aerial guideway design within a narrow interstate corridor, balancing constructability, durability, and cost

Long-span I-5 crossing redesign,optimizingstructural configuration to reduce cost whilemaintaininguninterrupted transit operations and median station access

Underpinning and protection of existing structures, including bridge abutmentsadjacent tonew guideway construction

Complex utility and wall coordination, requiring staged construction and structural accommodation for relocations

Retaining systems and at-grade transitions, addressing geotechnicalconstraintsandmaintainingcorridor stability

The project required extensive coordination with multiplejurisdictionsand stakeholders, including WSDOT and the Cities of Seattle, Shoreline, Mountlake Terrace, and Lynnwood. Structural design solutions were developed to navigate right-of-way limitations,maintaintraffic operations, and integrate with existing bridges, roadways, and transit facilities.

When Cheap is Expensive Elmer

Timby and the Origins of QualificationsBased Selection
