 Along the entire length of the motorway, the European route E233 follows the A37.Until 2003, the main connection between Hoogeveen and the German B402 road was the two-laned N37 highway.In that year, construction of the motorway finished on the section between interchanges Hoogeveen and Holsloot and that part of the road, now upgraded from 'N37' to 'A37', was opened to traffic.
