The dirty tracks

For the past three months, a local primary school has been undergoing expansion. Naturally, this has led to construction vehicles becoming a common sight down the main road out of our neighbourhood. The construction area itself is dirty, so when those vehicles go back onto the road...

...they leave dirt prints behind them. While this part of the road doesn't look particularly dirty, it is because it's about a hundred yards from the school and by the time vehicles reach it, most of the dirt has come off the tyres. It's the entrance to the school that looks a mess, or at least it did until it rained today. The new-found cleanliness won't last for long, however: the construction is still ongoing and the dirt will return once the rain stops or it'll become mud before then (or already is).
