MKAD (Minsk)

From Wikipedia, the free encyclopedia

MKAD is the name of the beltway that goes around Minsk, Belarus. The name is an abbreviation that means Minsk Ring Automobile Road (Russian: Минская кольцевая автомобильная дорога). The 56.2 km road straddles the Minsk city limits.

[edit] History

The road was built between 1956 and 1963. In the beginning the road had just one lane in each direction and the width of the roadway was 7.5 meters. Reconstruction began in 1980. The result was 26.8 km with four lanes with the remaining section, 29.4 km, having two lanes.

[edit] Recent developments and current conditions

At the end of the 1990s, the road was used by 16,000-18,000 automobiles daily and had level crossings, traffic lights and bus stops. Thus, on August 7, 2001, president Alexander Lukashenko ordered its reconstruction, with the completion due by November 2002.

The rebuilt road opened on November 7, 2002. MKAD has come closer to resembling a freeway, due to the elimination of traffic lights, the prohibition of left turns at grade level, and the installation of streetlights along its entire route. It has a total of six lanes, a width of 29 meters, and a capacity of 85,000 vehicles per day. The road was designed to have a 120 km/h speed limit, though at present the limit is 90 km/h. This restriction is due to frequent accidents involving people crossing in undesignated places, despite the fact that there are more than 50 pedestrian crossings and barriers on both sides of the road designed to prevent pedestrian intrustion.

There are three weight stations along the road. The roadway has implanted devices that measure surface condition, dewpoint, wind speed and direction, visibility, air temperature and other parameters. This information is transmitted to the central office, where officials can decide whether to treat the road surface to prevent it from freezing. The devices also measure the speed and frequency of road traffic. There are also electronic signboards with information for motorists.

Reconstruction required the laying of 680 tons of asphalt concrete, the installation of 100 km of pedestrian barrier and 2.4 km of sound barrier, and the construction of 24 interchanges, 30 bridges and viaducts, 6 above-ground pedestrian crossings and 16 underground pedestrian crossings.

As of 2006, the road was used by 50,000 vehicles a day. 93.4% of the vehicles were cars and vans, 5.8% were trucks and 0.8% were buses. Actual speeds were as follows:

• below 70 km/h: 13.3% of vehicles
• below 90 km/h: 53.4%
• above 90 km/h: 33.3%
