Why Your Commercial Development Is Stuck

These are the real roadblocks we see every day. The good news — each has a proven engineering solution.

🛑

Construction Halted by KeNHA?

Access permits require certified Road Safety Audits and approved junction designs. Without them, your project sits idle and costs escalate.

📐

Struggling to Design Deceleration Lanes?

KeNHA has specific geometric design standards for deceleration lanes, acceleration lanes, and sight distances. Non-compliance means rejection.

📋

Need a Certified Road Safety Auditor?

Only EBK-registered engineers with specific RSA certification can produce the reports KeNHA and KURA require for commercial access permits.

Designed, Audited & Approved

Each of these junctions was designed, audited, and submitted — all securing full KeNHA approvals.

Frequently Asked Questions

How much does a Road Safety Audit (RSA) cost in Kenya?
RSA costs depend on the road class (KeNHA/KURA) and physical design length. Strasan Group provides a detailed custom proposal based on preliminary feasibility reviews. Typical engagements range from KES 150,000 to KES 450,000 depending on complexity.
Who is authorized to sign off on a KeNHA Road Safety Audit?
Only EBK (Engineers Board of Kenya) certified Lead Road Safety Auditors holding accredited postgraduate credentials can stamp audits for highway clearances. Strasan Group has multiple EBK-registered Lead Road Safety Auditors on staff.
What is the difference between KeNHA and KURA access permits?
KeNHA (Kenya National Highways Authority) handles access permits for national highways (Class A and B roads). KURA (Kenya Urban Roads Authority) handles permits for urban and municipal roads. Each has different design standards, application processes, and approval timelines.
How long does the KeNHA access permit approval process take?
The approval process typically takes 6-12 weeks from submission of a complete application package. This includes: Road Safety Audit report, junction design drawings, Traffic Impact Assessment, and all statutory forms. Strasan Group helps fast-track this process with properly prepared submissions.
What are the key design requirements for a commercial access junction?
Key requirements include: deceleration lanes (minimum length based on road speed), acceleration lanes for merging, sight distance (minimum 200-400m depending on road class), turning radii for design vehicles, and drainage provisions. All must comply with KeNHA or KURA geometric design standards.
