After doing Bypass, toothdoctor and myself found ourselves in Rainbow Junction. The downstream culvert of Macro leads on from this, it's double barreled at the infall, but opens up to 3 someway in.
A short water slide greeted us almost straight away and hinted this was going to be good. The box section soon opened up into a beast of a 12 ft RCP, Before long a large shaft rose above the pipe.
A brick channel culvert takes the Chorlton Brook under Platt Field Park.
