Castle Street improvements
Improvements being made
We will upgrade the temporary pop-up cycleway to a permanent segregated cycleway along Castle Street and improve:
- bus stops along Kingsway and North Road,
- paving,
- drainage,
- street lighting,
- signage, and
- road surfacing.
The upgraded cycleway will stay on the north side of Castle Street. We will need to make changes to key junctions and small changes to the loading bays.
There are no major changes to lane allocation.

Changes near Cardiff Castle
Any works located immediately adjacent to the castle require a Scheduled Monument Consent application. CADW has approved both the application and the proposed design, and they are overseeing the works on site.
When the work is taking place
The work is due to start in January 2026 and expected to run until January 2027. This will be confirmed once we have appointed a contractor.
We plan to start the work at the Kingsway junction and work round towards Westgate Street.
