The Moscow Automobile Ring Road (Russian: Московская кольцевая автомобильная дорога, romanized: Moskovskaya koltsevaya avtomobilnaya doroga), or MKAD (МКАД), is a ring road running predominantly on the city border of Moscow with a length of 108.9 km (67.7 mi) and 35 exits (including ten interchanges).
Although not yet a freeway, it featured interchanges at major junctions, very few traffic lights, and a speed limit of 100 km/h (62 mph).
In December 2002 Bulvar Dmitriya Donskogo became the first Moscow Metro station that opened beyond the limits of MKAD.
[1] In 1995–1999, the road was widened from the initial four to ten lanes, while all intersections became grade-separated, bridges were built to accommodate pedestrians, traffic lights were removed, and a solid concrete barrier was installed in the median.
In 2001, all slow-moving vehicles were banned from entering the MKAD, and the renovated road received a freeway designation from the mayor's office.
