What is Highways Design and Why It Matters?
Highways design plays a critical role in development — from securing planning permission with compliant access proposals, to delivering adoptable infrastructure ready for local authority approval. At Flood Risk Consult, we offer highways and external works design services that support every stage of the project lifecycle — from initial concept through to detailed design, construction, and post-completion support.
Our highways design services are tailored for both private developers and public sector bodies, with solutions that meet the standards of local authorities, highway departments, Section 278/38 requirements, and the Design Manual for Roads and Bridges (DMRB).
Concept to Completion: Full Lifecycle Support
We provide a start-to-finish design service, including:
Concept access design for outline applications
Preliminary layout plans to support planning and masterplanning
Detailed highways design for construction and adoption (Section 278/38)
Technical submissions for Highways Authorities and Design Checks
Swept path and visibility splay analysis
Construction support and on-site coordination
Whether working as lead designer or as part of a multidisciplinary team, we coordinate across drainage, levels, statutory undertakers, and landscaping, ensuring every access or road scheme integrates seamlessly with the wider development.
We Liaise With:
Local Highway Authorities (Section 38 & 278 agreements)
Transport consultants and masterplanners
Utility providers for crossings, ducting, and diversions
Planning officers, road safety auditors, and Building Control
Site contractors and engineers during construction phase
Who We Support:
Housebuilders and developers submitting Section 278 designs
Architects and masterplanners coordinating access and movement
Transport consultants requiring technical support for drawings
Contractors needing construction-ready detail for delivery
Planning consultants looking for access strategies or highways notes
What Can We Design?
We have experience designing the full range of highways and access infrastructure:
🛣️ Road Infrastructure

Section 278 / Section 38 design packages
🚦 Junctions & Access
Priority (T-junction and crossroads) junctions
Roundabouts (mini, compact, standard)
Signalised junctions and upgrades
Vehicle crossovers and dropped kerbs
Ghost islands, right-turn lanes, and channelisation
🚶 Pedestrian & Cycle Infrastructure
Footways and shared cycle routes
Zebra and signalised pedestrian crossings
Raised tables, tactile paving, and drop kerbs
School and pedestrian safety measures
📍 Signage & Markings
Road signage schedules and regulatory signage layouts
Road marking (lining) schemes and layout plans
Advance direction signs and site-specific directional signage
🚛 Design Analysis & Compliance

Vehicle tracking using AutoTrack / Civil 3D
DMRB-compliant technical notes
We bring a pragmatic, responsive approach to highways design — combining engineering rigour with planning insight. Whether it’s a quick-turnaround access plan or a fully adoptable road scheme, we understand what authorities need and what your project demands.
With over two decades of civil engineering experience, we don’t just draw compliant roads — we design infrastructure that gets approved, gets built, and gets adopted.
