As of this week, the Moscow Ring Road-Profsoyuznaya Street interchange will stop being the most unpopular junction in Moscow. The old-fashioned cloverleaf interchange has been replaced by four flyovers, an underpass, side roads and lay-bys.
How traffic patterns will change
The principle “divide and conquer” works for both politics and road construction. The Moscow Ring Road-Profsoyuznaya Street interchange was designed to provide a separate traffic flow and to separate on- and off-ramp traffic. This approach will raise traffic capacity considerably.
Two side roads, each three lanes wide, have been added parallel to the MKAD around the new interchange. Those heading for Kaluzhskoye Motorway or Profsoyuznaya Street will use these relief roads, staying out of the main traffic flow. Acceleration lanes and lay-bys for buses have also been built along the MKAD to maintain higher average speeds.
Another overpass will allow motorists to drive from Kaluzhskoye Motorway to the clockwise side of the MKAD. Motorists going to the Moscow Region from the clockwise side of the MKAD will use a tunnel over a kilometre long. The other three exits from the cloverleaf have been widened and left in place. The last overpass is located a little farther and provides a U-turn from the anticlockwise to the clockwise side of the MKAD.
In addition, Kaluzhskoye Motorway has been widened to four lanes in each direction, side roads along the Mega Mall have been rebuilt to stop the circular pattern in their area and an access point from Kaluzhskoye Motorway has been put in. The total route length of the new road sections is 13.35 kilometres.
Who will use the new interchange
This progress will primarily be appreciated by motorists and bus passengers commuting from the Troitsky and Novomoskovsky Administrative Areas. Now their travel time will be shorter and there will be less risk of getting into hour-long traffic congestion. Residents in the Tyoply Stan and Yasenevo districts will also find it easier to get home.
This section of the Moscow Ring Road will also be relieved. Traffic will be able to transition to a different direction without the intertwining common to the cloverleaf design. Removing the construction restrictions will also improve the situation. For the first time in several years the road surface is smooth, with permanent striping and the former speed limits.
Shoppers will stop interfering with the main traffic streams. It will be possible to get to the large malls in the area via the side roads and using the U-turn from Kaluzhskoye Motorway. The Food City agriculture cluster will also be easier to reach.
From construction to completion: changes in the Profsoyuznaya Street interchange
The MKAD-Profsoyuznaya Street interchange is one of 33 two-level interchanges along the MKAD. Traffic was originally launched in 1962. The junction acquired its modern look 35 years later, after the Moscow Ring Road was rebuilt in 1996-1997. However, another decade later it became clear that cloverleaf interchanges lacked efficient traffic handling capacity. Starting in 2011, cloverleaf interchanges started being replaced by flyover interchanges.
The Profsoyuznaya Street-Moscow Ring Road project began in February 2015. To finish more quickly, the summer and autumn work was non-stop, using three shifts, 24-hours a day. The two metro stations nearby, Konkovo and Tyoply Stan, complicated matters. Contractors had to relocate the high-voltage lines and water drainage systems resulting in 20 kilimetres worth of new utility lines around the interchange. Kaluzhskoye Motorway was rebuilt at the same time.
