Cross-border operations: Many Southern Pennsylvania projects require coordinated staging, permitting reviews, and material logistics that cross the Maryland state line. LADMA's familiarity with both PennDOT and MDOT SHA procedures supports continuity for projects spanning the PA/MD border — including I-81, US-11, US-15, and US-30 corridor work.

Traffic Control Services in Southern PA
From short-duration flagging operations to multi-phase roadway projects requiring full traffic control services coordination, our capabilities are structured around the compliance and documentation standards Pennsylvania contractors and agencies require.
-
Flagging & Lane Closure Operations
Temporary traffic control setups for construction and maintenance activities on state routes, local roads, and utility corridors. Operations are staffed by trained flaggers working to MUTCD-compliant standards and PennDOT work zone requirements.

How Deployment Works
A defined process from initial contact to on-site execution ensures your project documentation, permits, and field setup are coordinated without delays.
Scope & Documentation Review
We review your project scope, applicable TCP or MOT plans, permit requirements, and any PennDOT coordination items. If no TCP exists, we can refer engineer contacts or work from standard configurations.
Logistics & Schedule Alignment
Equipment staging locations, crew scheduling, and permit timing are confirmed with your project manager. Cross-border logistical considerations for PA/MD corridor projects are addressed at this stage.
Field Setup & Execution
Flaggers, equipment, and supervisory staff are deployed to your site per the approved traffic control configuration. Setups adhere to MUTCD standards and your project-specific TCP requirements.
Closeout & Documentation
Daily jobsite documentation is maintained throughout the project. At closeout, records are available to support inspection, billing, and compliance reporting requirements.
Compliance & Procurement Readiness
General contractors, municipalities, and utility owners operating in Southern Pennsylvania require subcontractors who can meet documentation, compliance, and coordination standards without escalating the administrative burden on the prime. Our operations are structured around the requirements of the Manual on Uniform Traffic Control Devices (MUTCD) and PennDOT Publication 213 — the governing frameworks for temporary traffic control on Pennsylvania roadways — and are designed to support procurement-level requirements from the start of a project engagement.
- Field operations align with MUTCD Part 6 temporary traffic control standards
- PennDOT Publication 213 work zone coordination guidance observed for applicable projects
- Daily field documentation available for inspection and project recordkeeping
- Supervisory personnel available for pre-construction meetings and site walk coordination
- Equipment and personnel configured to TCP specifications provided by engineer of record
Industry standards: Flagging operations and work zone safety practices follow training and certification benchmarks established by the American Traffic Safety Services Association (ATSSA), the national trade organization for the traffic control industry.
-
MUTCD Alignment
All temporary traffic control setups follow the MUTCD standards applicable to Pennsylvania work zones, including sign spacing, taper lengths, and flagger positioning requirements.
-
PennDOT Coordination
For projects on state-maintained routes, we work within the framework of PennDOT Highway Occupancy Permit (HOP) and utility accommodation requirements, coordinating with prime contractors on permit compliance and Publication 213 traffic control plan adherence.
-
Jobsite Documentation
Project files include daily logs, equipment deployment records, and personnel certifications. Documentation packages are structured to support general contractor QA/QC requirements and agency inspections.
-
Industry Training Standards
Work zone personnel training and flagger qualification align with professional standards maintained by the American Traffic Safety Services Association (ATSSA), supporting consistent, safety-oriented field performance across all project types.
Representative Projects
The following project types reflect the range of work zone scenarios our teams handle across Southern Pennsylvania and the broader Mid-Atlantic region. View our full project history.
-
Utility Corridor Work — Multi-Phase Lane Closures
Multi-phase flagging and lane closure support for a utility installation project on a high-volume state route. Operations included alternating one-way traffic control with TCP-compliant signage sequences across a phased construction schedule.
-
Urban Pedestrian Control — Downtown Corridor
Pedestrian and vehicular traffic management for a downtown streetscape rehabilitation project. Setup included sidewalk closure detours, ADA-compliant pedestrian crossings, and coordination with municipal traffic engineering for signal timing adjustments.
-
Night Lane Closure Support — Interstate Rehabilitation
Nighttime rolling and stationary lane closure operations supporting a pavement rehabilitation contract on a limited-access highway. Work included TMA positioning, arrow board deployment, and coordination with the prime contractor for shift handoffs.
Traffic Control in Southern Pennsylvania
-
In most cases, yes. PennDOT requires a Traffic Control Plan for work on state-maintained roads, particularly those involving lane restrictions, detours, or work within the travel lane. The specific requirements depend on roadway classification, speed limit, and the nature of the work. Your Highway Occupancy Permit or utility accommodation permit will typically reference TCP requirements. We can help coordinate field execution once an engineer-stamped plan is in place — or refer you to qualified TCP engineers if you need a plan prepared.

Our Southern Pennsylvania service area covers York, Lancaster, Adams, Franklin, and Cumberland counties — including major project locations in York, Hanover, Lancaster, Gettysburg, Chambersburg, Waynesboro, Carlisle, and Mechanicsburg. For projects near the Maryland border, we also coordinate with our Maryland operations team for cross-border logistics.
-
Yes. LADMA operates across both Maryland and Pennsylvania, which makes us well-suited for projects on multi-state corridors like I-81, US-15, US-11, and US-30. Cross-border projects often involve coordination between PennDOT and MDOT SHA permit requirements, and our team is experienced in managing logistics across both jurisdictions without adding burden to the prime contractor.
-
We maintain daily field documentation including deployment logs and personnel records. Insurance certificates and additional insured endorsements are provided prior to mobilization per contract requirements. Supervisory personnel are available for pre-construction meetings and can attend site inspections when required by the prime contractor or project owner.
-
Mobilization timelines for short-notice or emergency deployments depend on current scheduling and resource availability in your area. Contact our dispatch team directly at 240-861-5050 for the fastest response. We'll confirm availability and discuss logistics in that initial call.
-
Yes. We work with municipalities, townships, and county agencies across Southern Pennsylvania on maintenance, rehabilitation, and capital improvement projects. Our documentation and compliance processes are structured to support public-sector procurement requirements, and we're experienced with the coordination steps involved in publicly funded work including pre-construction submittals and agency inspection protocols.
