This stretch of 71 as well as everything south towards the River was reconstructed and rerouted between 1993 and 2000.

The river here has changed course a lot over the last century, especially this bend. Mapping the smoothness of the course changes might be challenging, but is definitely doable

Both roundabouts came *after* the new 237 was constructed, these are placeholders for now until the pre-roundabout layouts are mapped

Start/end dates for features will be added when I look into them, for now this is something to start off of
