A brand new railway cycle route in western territory - though an LNWR^▸ (London North Western Railway) line this time rather than GWR^▸ (Great Western Railway). Carmarthenshire Council is building a cycleway along the old Carmarthen–Llandeilo line. The first (Carmarthen-end) half is now open: https://www.carmarthenshire.gov.wales/business/development-and-investment/tywi-valley-path/

Completion to Llandeilo by the end of the year, including two new river bridges. I think this is the biggest new railway path project in the UK^▸ (United Kingdom) for some years, though there are a few short paths bubbling under.
