On its way, it crosses three Dutch provinces: South Holland, Utrecht, and Gelderland.This part of the road, known as the Utrechtsebaan, is too narrow to meet the Dutch requirements for a motorway (for example, it does not have a shoulder), and is therefore a highway with a maximum speed of 70 km/h.In 2008, a government programme on route branding, under an umbrella project in urban planning, put stickers on all streetlights of the A12, citing efforts to give it a "route 66-like" allure.This plan, dubbed the "regenboogroute" (rainbow route), received news coverage because of its alleged trivial results (stickers on streetlights) and high costs (€120 000).[1] The Utrechtsebaan has been the location of numerous blockades by the climate group Extinction Rebellion.
