That has been very common here in the UK for several years, particularly when there is a lot of construction and repair work for several miles on motorways. There are "averaging" speed cameras at the start and end of the roadworks, and at intervals too along the way (and always at sliproads for those entering and leaving the motorway within the roadworks). The first notice you get if you've been speeding is a letter of intending prosecution which suddenly arrives several days after you've driven along that stretch of road!
