At MZB Engineering, we specialize in Engineered Temporary Traffic Control Plans (TTCPs) for construction, utility, roadway, and infrastructure projects. Our approach combines MUTCD requirements, agency-specific standards, practical construction knowledge, and sound engineering judgment to develop plans that protect road users, pedestrians, and workers while supporting the contractor’s means, methods, and project schedule.

Because no two projects or jurisdictions are exactly alike, we do more than place signs and devices on a drawing. We work with our clients to understand how the work will actually be constructed, evaluate feasible closure strategies, and develop a traffic control approach that is practical, constructible, and responsive to the reviewing agency’s expectations.

A Collaborative, Engineering-Driven Approach

For most projects, we begin with a Microsoft Teams coordination meeting with the client. We treat this meeting as a working session—not simply a project handoff. Our team reviews the scope, construction sequence, work area, traffic conditions, access needs, and proposed closures with the people who will build the project.

  • Collaborative Scope Review: We discuss the proposed work, construction methods, work limits, access constraints, and anticipated traffic impacts directly with the client.
  • Closure Strategy & Engineering Guidance: We discuss which lane, shoulder, intersection, flagging, detour, or other closure concepts may be appropriate under the MUTCD and applicable agency requirements and identify concepts that may not be feasible or acceptable.
  • Agency-Specific Experience: Having worked with more than 500 agencies across the country, we bring practical knowledge of how requirements and review expectations can vary by jurisdiction, roadway environment, traffic demand, and project type.
  • Live Phasing Workshop: For complex work, we can develop the initial construction phasing and traffic-handling concept during the Teams meeting, incorporating the client’s input in real time before detailed plan production begins.
  • Client-Informed Design: By resolving key questions early, the first plan submittal already reflects the client’s construction needs, reducing avoidable redesign and improving coordination.

A closure that may be workable in one jurisdiction may not be appropriate in another. Dense urban areas with high traffic volumes can have very different operational constraints from lower-volume communities. Our experience helps clients identify these issues early and select a strategy that is more likely to satisfy both project needs and agency expectations.

Why Choose MZB Engineering for TTCPs?
  • Engineering Judgment: Plans are developed using MUTCD guidance, applicable agency standards, site conditions, traffic operations, and professional engineering judgment—not a one-size-fits-all template.
  • Collaborative Planning: Microsoft Teams working sessions help us understand the project before design begins and allow the client to participate in closure and phasing decisions.
  • Extensive Agency Experience: Experience working with 500+ agencies nationwide helps us anticipate jurisdiction-specific expectations and common review concerns.
  • Quick Turnaround: We prioritize responsive delivery and can accommodate expedited schedules when project scope and workload allow.
  • Unlimited Revisions at No Extra Cost: We revise our traffic control plans as needed in response to client or agency comments without additional design fees for revisions within the original project scope.
  • Multi-State Licensed Engineering: MZB Engineering is supported by professional engineering licensure in 9 states, allowing us to serve clients across multiple jurisdictions with engineering oversight appropriate to the project.

Start Your Project with Confidence

A successful traffic control plan must work on paper, in the field, and through agency review. MZB Engineering combines engineering judgment, client collaboration, nationwide agency experience, and responsive support to develop plans that are practical for construction and tailored to the roadway and jurisdiction where the work will occur.

After submittal, our support continues. If review comments or questions arise, we can meet with the client to review them together and, when appropriate, participate in an over-the-shoulder review with the agency or reviewer. For complex projects, resolving technical questions collaboratively can reduce back-and-forth review cycles and help keep the approval process moving.

Engineering Review & Client Support

Professional Engineering Oversight: Our traffic control plans receive engineering oversight with emphasis on safety, constructability, applicable standards, and sound engineering judgment. Depending on the jurisdiction and project requirements, plans can be prepared and signed/sealed by the appropriately licensed professional engineer.

Proven Agency Experience: Our team has worked with more than 500 agencies across the country. That experience helps us recognize that agencies may interpret or supplement work-zone requirements differently based on local policy, roadway classification, traffic volumes, community impacts, and other project-specific conditions.

Responsive Through Approval: We stay engaged after the initial submittal, review comments with our clients, revise plans within the original scope at no extra cost and help address reviewer questions so issues can be resolved efficiently.

Frequently Asked Questions (FAQ)

A traffic control plan is an engineered set of drawings that shows how traffic, pedestrians, cyclists, and workers will be safely accommodated through or around a construction work zone. It may include signs, channelizing devices, lane or shoulder closures, flagging operations, detours, pedestrian routing, traffic shifts, and construction phasing. MZB develops each plan around the project scope, applicable MUTCD guidance, agency requirements, site conditions, and engineering judgment.

MZB’s traffic control plans are developed by experienced traffic control professionals with professional engineering oversight. MZB Engineering maintains professional engineering licensures in 9 states, and projects are handled in accordance with the licensing and sealing requirements of the applicable jurisdiction.

Traffic control plan pricing depends on the project scope, location, roadway conditions, number and type of closures, construction phasing, and reviewing jurisdiction. We provide project-specific pricing and clearly define the design scope before work begins. Revisions within the original project scope are provided at no extra cost.

Our plans are developed using the applicable MUTCD provisions together with state and local agency requirements and project-specific engineering judgment. Because agency requirements can vary, we also incorporate jurisdiction-specific criteria and lessons learned from our experience working with more than 500 agencies nationwide.

Turnaround depends on the size and complexity of the project, but responsive delivery is a core part of our service and expedited schedules may be available. We also provide unlimited revisions at no extra cost for changes within the original project scope and remain available to help address agency review comments.
