Minnesota State Highway 55 (MN 55) is astate highway that runs 221 miles (356 km) across the central part of state taking a diagonal route from its western most at the North Dakota state line nearTenney to its easternmost point at the intersection withU.S. Highway 61 (US 61) inHastings. In Minneapolis and Golden Valley, portions of the route are also signed asOlson Memorial Highway.

MN 55 serves as a northwest–southeast route between Elbow Lake, Glenwood,Paynesville,Annandale,Buffalo,Plymouth,Minneapolis,Mendota Heights, andHastings.

MN 55 begins at theBois de Sioux River, at the Minnesota—North Dakota state line nearTenney.North Dakota Highway 11 (ND 11) is its counterpoint upon crossing the state line. MN 55 continues east to Tenney,Nashua, andWendell. The route has a junction withU.S. Highway 59 (US 59) before entering the city of Elbow Lake. US 59/MN 55runs concurrently for 11 miles (18 km) until reachingBarrett.

MN 55 then continues independently again toHoffman,Kensington,Farwell, andLowry before reaching the city of Glenwood. At Glenwood, MN 55 has an intersection withMN 29 and an interchange withMN 28.

The route continues southeast toSedan andBrooten before reaching its junction withUS 71 inBelgrade. MN 55 passes throughRegal before reaching its junction withMN 4 andMN 23 at the city ofPaynesville.

MN 55 continues east toEden Valley andWatkins before reaching its junction withMN 15 atKimball.

The route has a junction withMN 24 in Annandale. MN 55 continues toMaple Lake and then Buffalo, where it has a junction withMN 25.

MN 55 enters theTwin Cities area atRockford andGreenfield, continuing east toMedina andPlymouth. MN 55 has a junction withInterstate 494 (I-494) in Plymouth. MN 55 continues east and has a junction withUS 169 at the Plymouth–Golden Valley boundary line. MN 55 continues through Golden Valley to its junction withMN 100. The route then continues east and enters the city ofMinneapolis.

The highway has been designated Olson Memorial Highway,^[2] named forFloyd B. Olson, a popular Minnesota governor of Norwegian ancestry. Olson grew up in North Minneapolis, near where the highway runs. While the entire route is designated as the Olson Memorial Highway, it is only consistently signed as such between Interstate 494 and N 7th Street in Minneapolis. The part of MN 55 southeast of downtown is known as Hiawatha Avenue.Light rail trains on theBlue Line, andLittle Earth Trail andHiawatha LRT Trail for bicyclists/pedestrians, run parallel to the highway for much of the Hiawatha Avenue stretch.

MN 55 runs concurrently alongI-94/US 52. MN 55 exits just before downtown at the westbound I-94/northbound US 52 exit, and leaves the concurrency at the exit for the Olson Highway, marked with the MN 55 shield. Eastbound, MN 55 leaves the Olson Highway at the interchange for I-94 eastbound/US 52 southbound, and leaves the freeway at the exit for Hiawatha Avenue, which is also marked with the MN 55 shield.

There has been some controversy with expansion of the highway.^{[citation needed]} An area known asCamp Coldwater, considered by some as the "birthplace of Minnesota", was dug up during some construction. MN 55 joins withMN 62 at this point.

Fort Snelling State Park is located near the junction of MN 55 andMN 5. The park entrance is located on MN 5 at Post Road.

MN 55 crosses theMinnesota River via the Mendota Bridge, which was the longest continuous bridge made of pouredconcrete when it was completed in 1926. It is 4,119 feet (1,255 m) in length.

The route entersMendota Heights, diverges from MN 62, and then has a junction withMN 13.

MN 55 continues southeast throughEagan, joining briefly withMN 149. The route then has a junction withMN 3 inInver Grove Heights. MN 55 then runs concurrently withUS 52 through Inver Grove Heights and intoRosemount. At Rosemount, MN 55 leaves US 52. MN 55 continues independently again to its eastern terminus at its intersection withUS 61 in the city ofHastings.

MN 55 was authorized in 1933.^[3]

The original alignment for MN 55 inMinneapolis was along oldUS 52 (nowCounty State-Aid Highway 81, CSAH 81) to Rockford Road, then Rockford Road to MN 55's present-day alignment (nowCSAH 9). The present-day alignment was constructed in the early 1950s.^[3]

In July 2005, the section of MN 55 that runs through downtown Minneapolis was turned back to local maintenance. To fill the gap, MN 55 was rerouted alongI-94/US 52.
