Very nice bridge not for traffic though as it’s a single lane track with passing gaps for pedestrians.

It's a beautiful canal but what is amazing is that it runs all the way to Brecon

If riding across bridge into Crick, take the first right hand road (next to the pub) to avoid traffic going up the hill and into town. It also takes you straight tup to the high st.

A wooden drawbridge carried the road over the canal and was replaced by a fixed bridge after navigation on the canal ceased in the 1930s. Before the canal reopened to boats in 1970, a steel drawbridge with an electric operating mechanism was installed. There are four other drawbridges along the canal to the west. They are for farmers to access fields and are less elaborate than the one at Talybont. Drawbridges saved the canal company the expense of building stone bridges over the canal at these locations.
