Midwest Heavy Highway & Bridge Construction Company

Millstone Weber delivers comprehensive heavy highway and bridge construction across Missouri, Illinois, Colorado, and throughout the Midwest. With over 95 years of proven project delivery, we provide the self-performed capabilities and project management depth that complex transportation infrastructure projects demand.

From major interstate reconstructions to bridge replacements and interchange improvements, we understand the challenges of building within active traffic corridors. Our approach combines strategic planning, accelerated construction methods, and a deep understanding of DOT requirements to deliver quality results on schedule while maintaining public safety and minimizing disruption.

Heavy Highway & Bridge Construction

Millstone Weber specializes in comprehensive transportation infrastructure construction spanning highways, interstates, bridges, interchanges, and supporting roadway systems. Our construction expertise covers every phase of work: from initial demolition and earthwork through final pavement placement, bridge deck construction, and traffic systems installation.

Our heavy highway and bridge construction capabilities include:

  • Highway and interstate reconstruction including full roadway replacement and major rehabilitation
  • Bridge construction and replacement from single-span structures to complex multi-span bridges
  • Interchange construction including complex grade separations and SPUI configurations
  • Concrete roadway paving with stringless technology and GPS-guided placement
  • Earthwork and excavation including mass grading, cut and fill operations, and site preparation
  • Drainage systems including storm sewers, culverts, and detention structures
  • Utility relocation for water, sewer, gas, electric, and communications infrastructure
  • MSE retaining walls and other soil stabilization structures
  • Roundabout construction and traffic calming installations
  • Tunnel and underpass construction including box culverts and rail grade separations
  • Bridge demolition and removal of existing structures

Design-Build & Accelerated Transportation Delivery

Millstone Weber brings extensive design-build experience to transportation projects, allowing us to deliver complex highway and bridge construction on accelerated schedules. Our design-build approach integrates construction expertise into the design phase, resulting in more buildable solutions, reduced project timelines, and better cost control.

This approach allows us to begin demolition, earthwork, and foundation work while design teams finalize details. The result: compressed project schedules without sacrificing quality.

Our design-build capabilities include:

  • Collaborative design phase participation working alongside engineering teams to develop constructible solutions
  • Value engineering to optimize designs for cost, schedule, and long-term performance
  • Fast-track construction beginning site work and early phases while final design is completed
  • Integrated project delivery with single-source accountability from design through construction
  • Phased construction planning to minimize traffic disruption and maintain corridor access

DOT & Public Infrastructure Expertise

Millstone Weber has built lasting relationships with MoDOT, IDOT, and CDOT through decades of successful project delivery. We understand that DOT projects require more than technical construction capabilities – they demand proven project management, meticulous documentation, and the ability to adapt to changing conditions while keeping the public safe and traffic moving.

Our DOT project experience includes:

  • Extensive MoDOT, IDOT, and CDOT project history spanning interstate reconstruction, bridge replacement, and corridor improvements
  • Complex bidding and procurement processes including design-build proposals and traditional design-bid-build competitions
  • Traffic management and maintenance of traffic (MOT) for high-volume corridors and urban interchanges
  • Public coordination managing community impact, access, and communication throughout construction
  • Railroad coordination for projects crossing or adjacent to active rail lines
  • Utility coordination working with multiple utility owners on complex relocations
  • Environmental compliance including erosion control, stormwater management, and protected species protocols.

Self-Performed Concrete Paving & Structures

We own and operate five portable concrete batch plants, maintain specialized bridge construction equipment, and deploy stringless concrete pavers. We don’t rely on subcontractors for the most critical elements of highway and bridge construction—our crews, equipment, and quality control processes deliver the structural integrity and surface tolerance that transportation infrastructure requires.

Our self-performed services include:

  • Bridge demolition including controlled removal of existing structures
  • Deep foundation work including drilled shafts and driven piles
  • MSE wall construction and soil retention systems
  • Box culvert and drainage structure construction
  • In-house surveying and 3D modeling for precision grading and layout
  • Concrete roadway paving for highways, interstates, and local roadways
  • Bridge structure construction including piers, columns, abutments, and deck placement
  • Concrete production using on-site portable batch plants for quality control and schedule flexibility
  • Stringless paving with GPS-guided placement for precise elevation control
