Route 20 (known locally as Lagimodiere Boulevard or Lag (lazh) is a city route in Winnipeg, Manitoba, Canada. It is the portion of Highway 59 within Winnipeg.
At about 16.7 km (10.4 mi), it is one of the longest roads in the city. It begins in the northeast, running through the suburb of North Kildonan before becoming the boundary between the suburbs of East Kildonan and Transcona. South of the CNR Redditt line, it enters the eastern section of St. Boniface, passing by the CNR Symington Yards and the Royal Canadian Mint before crossing the Perimeter Highway and leaving the city in the extreme southern part of St. Boniface.
Route 20 maintains expressway standards through Winnipeg, generally as a 4-lane divided route, and has an 80 km/h (50 mph) speed limit for the most part, except for a brief section in the north end at Regent Avenue where the speed limit drops to 70 km/h (45 mph).
Lagimodiere Boulevard was named after Jean Baptiste Lagimodière, an early pioneer of St. Boniface.
