London bus routes will be undergoing changes throughout the upcoming weekend, with many bus routes facing school holiday timetables.

TfL buses align with the Mayor’s Transport Strategy aiming for 80 per cent of journeys via foot, bike, or public transport by 2041.

There is currently a bus fleet of around 9,300 buses which follow across 675 different routes.

The latest timetable changes are in place to help “match demand, deliver value for money and allow TfL to invest in outer London”.

The following timetable changes will take place from Saturday July 20:

Route 17 will have a new timetable from this date with minor changes to times. The Sunday daytime frequency will be increased to a bus every 12 minutes.

No change to the frequency at any other time. The times of first buses will also change on Sundays with first buses retimed to depart at the same time as on Monday to Saturdays, 4.20am from Archway towards London Bridge and 5am from London Bridge towards Archway.

The temporary timetable will be removed from route 201 with the service returning to run every 15 minutes during the daytime on Monday to Saturdays, every 20 minutes during the daytime on Sundays and every 30 minutes during the evening on all days of the week.

Route 280 will have a new timetable on all days of the week with minor changes to times.

Route C11 will have a new timetable on all days of the week with minor changes to times.

Route W8 will have a new timetable on all days of the week with minor changes to times.

School Holiday schedules will be in operation on the following routes:

18, 20, 27, 32, 39, 51, 53, 54, 60, 61, 62, 63, 66, 69, 70, 71, 75, 77, 81, 83, 86, 89, 90, 92, 96, 99, 103, 107, 108, 109, 110, 111, 113, 114, 119, 122, 127, 130, 131, 132, 134, 139, 140, 142, 143, 146, 150, 151, 154, 156, 157, 160, 161, 163, 164, 173, 174, 179, 181, 182, 183, 184, 185, 186, 191, 197, 204, 208, 210, 212, 213, 216, 222, 227, 229, 233, 240, 245, 248, 251, 252, 256, 257, 261, 262, 263, 264, 265, 267, 270, 273, 275, 278, 280, 281, 282, 285, 287, 290, 292, 293, 294, 296, 297, 302, 313, 314, 321, 326, 328, 331, 336, 337, 347, 352, 353, 358, 363, 364, 367, 368, 370, 371, 372, 375, 384, 385, 386, 396, 397, 401, 404, 406, 407, 412, 417, 418, 422, 432, 433, 434, 439, 444, 450, 463, 464, 466, 467, 473, 481, 483, 490, 493, 498, 499, B11, B14, B16, C10, C11, D3, E2, E8, EL1, H2, H3, H12, H13, H18, H19, H22, H28, H32, H37, H91, H98, K1, K2, K3, P5, P12, S2, S3, S4, SL6, SL7, W6, W8, W11, W13 and W15.
