Mitigation Design That Keeps Developments Moving

Practical highway improvement schemes designed for safety and approval.

At Grange Transport Consulting, we provide professional Mitigation Design for off-site junction improvements and highway works required as part of planning conditions or Section 278 agreements.


Our team delivers clear, buildable designs that address the impacts identified in Transport Assessments and Road Safety Audits, helping you secure technical approval and move your project forward efficiently.

What Is Mitigation Design?

Mitigation Design involves preparing detailed drawings and technical solutions for highway improvements or access changes required to make a development acceptable in planning or safety terms.


These works often include:

A curved arch design featuring a dark gray top stripe separated by a white line from a light blue stripe below.

Junction modifications or signal improvements

A graphic showing two curved, parallel bands, the top in dark gray and the bottom in light blue, against a white background.

Footway, cycleway, or crossing enhancements

Two curved bands, one dark grey and one light blue, set against a plain white background.

Traffic calming or visibility upgrades

A stylized, curved graphic design element featuring a dark grey arch above a light blue arch on a white background.

Localised widening, turn lanes, or new access junctions

Our designs are produced in accordance with Design Manual for Roads and Bridges (DMRB), Manual for Streets (MfS), and local authority requirements, ensuring a smooth path from planning to technical approval.

Our Approach

We focus on producing designs that are both technically robust and practical to deliver.


Our process begins by reviewing Transport Assessment or Road Safety Audit recommendations, identifying the necessary measures, and developing clear design drawings that address all requirements.


We collaborate closely with your design team, contractors, and the highway authority to refine details and achieve technical approval under Section 278 or Section 38 processes.


Every design is prepared using the latest CAD and design tools to ensure accuracy and clarity.
