Heads up for those who use the 171 or 172 to get into central London.
Looks like both routes are being shortened as of 15th June;
Route 171 will terminate at Elephant & Castle instead of Holborn. Advice is to change to routes 1, 68, 168 or 188 to reach Holborn.
Route 172 will terminate at Aldwych instead of Clerkenwell Green. Advice is to change to route 341 anywhere between Waterloo and Aldwych to continue on.
Summary of changes can be found here;
