Narrative:

Problem: taxied on a taxiway that was restr to single engine aircraft. The contributing problem was that a lot of construction was occurring on the taxiway that I use regularly. The taxi clearance was complex, including taxiing around a bump on a runway. This was my home base airport. Because of the complexity of the taxi clearance, I should make a copy of the airport diagram and draw, with a yellow marker, the taxi route. This is getting bad when you have to do this for an airport with which you are very familiar.
