 Small bridges in this section were initially built twice as wide as necessary, because a widening of the road was already anticipated in the original plans.The widening happened in 2011 and 2013, since then most of this busy section (except for the short section between M1 and M7) has got 4x(3+1 emergency) lanes, and speed limits were be raised to 110 km/h.The southern section upgraded to a six lane motorway was delivered between M1 and Highway 51 on 30 June 2013.
