A £4.25m upgrade project will replace two railway bridges in Pembrokeshire, commencing in 2019.
We will be replacing Pembroke Road railway bridge (which crosses Pembroke Road) and Milford Road railway bridge (which crosses the A4076 on Dredgeman Hill) both set in Merlins Bridge, Haverfordwest. The upgrade project is part of our Railway Upgrade Plan and will improve the resilience and reliability of the railway for passengers.

Both railway bridges, which carry the South Wales Mainline, require this essential work as part of our commitment to maintain a safe and reliable railway. Milford Road underbridge was last reconstructed in 1939. Pembroke Road underbridge was originally built in 1856 and the bridge deck was last reconstructed in 1937, and so both bridges are coming toward the end of their lifespan.
Alongside us, the primary contractor on site will be AMCO and we expect to begin preparatory work late this year.
During the core weekends of work at each bridge we will be:
- removing the rail track bed,
- demolishing and removing the existing bridge deck and returning it to the compound
- transporting the new bridge to site and fixing it in place
- completing drainage and waterproofing
- reinstating the rail track bed
- completing essential safety checks.
To ensure the core works are carried out as efficiently and safely as possible we will be required to temporarily close the roads (the A4076 and Pembroke Road) at separate times, for one weekend each.
Pembroke Road at the railway bridge will be closed from:
- 20:00 on Friday 18 January 2019 to 06:00 on Monday 21 January 2019.
The A4076 at Milford Road railway bridge will then close from:
- 19:00 on Friday 15 February 2019 until 06:00 on Monday 18 February 2019.
