The Western High-Speed Diameter (ЗСД, ZSD, Russian: Западный скоростной диаметр) is a toll motorway in Saint Petersburg, Russia.

Other sections of the highway were under construction and eventually formed a corridor through the western districts of St. Petersburg to cross the northern portion of the A118 beltway in Yuntolovo and to meet the E-18/M-10 route at the Beloostrov junction.

[1] It connects the northern terminus of the first open segment with the industrial western part of the Kirovsky district which hosts the port of St. Petersburg.

The Western High-Speed Diameter is an inner-city multilane highway, which made it possible to cross a 5-million metropolis in 20 minutes and provides 24-hour transport link between southern and northern districts of St. Petersburg.

The Central section of WHSD incorporates a whole complex of artificial structures and is considered the most challenging part of the road in respect of engineering solutions and construction process.

The Western High-Speed Diameter is a 46.6-kilometre road with a total length, including all exit and entry ramps and interchanges, of over 70 kilometres.

[2] Concerned citizens have formed a movement to save the forest and swampland of the nature reserve from harmful construction projects along the route of the new highway.
