In this article we shall be talking about the various roads that are within the city of Mendota Heights, as well as those roads nearby.

The southern terminus of I-35E is at exit 88A in Burnsville, where I-35 splits into I-35E and I-35W. While I-35W heads north into Minneapolis, I-35E takes a northeasterly path into Saint Paul. There is no access between I-35E and I-35W here, but Dakota County Road 42 (exit 88B), immediately to the north, connects the two Interstates in Burnsville. Major interchanges south of Saint Paul include State Highway 77 (MN 77, signed as Cedar Avenue—exit 92) at Apple Valley – Eagan and Interstate 494 (exit 99) in Mendota Heights. Between exits 94 and 97, the highway deviates from its relatively straight path to avoid Blackhawk Lake. As it crosses I-494, I-35E turns more to the north, crossing MN 110 (exit 101) and MN 13 (exit 102) in Mendota Heights before crossing the Mississippi River on the Lexington Bridge into the city of Saint Paul. This portion of I-35E is four lanes wide (two in each direction), except between MN 77 and MN 110, where it carries six lanes. The Lexington Bridge carries six lanes—four through lanes and the exit and entrance lanes for MN 13—as well as a bicycle and pedestrian path. The bridge has an innovative automatic anti-icing system that sprays potassium acetate onto the bridge surface to prevent frost and ice formation in inclement weather.

Exit numbering of Interstate 494 is unusual in that it begins at the Minnesota River heading westbound (between Mendota Heights and Bloomington), and continues clockwise around the entire beltway, continuing clockwise onto Interstate 694. The last exit east of the Minnesota River is #71 to Pilot Knob Road. The first exit west of the river is #1A, which grants access to eastbound State Highway 5 and airport terminal 1. The most significant landmark on the length of I-494 is Mall of America, just south of the intersection of I-494 and State Highway 77.

Highway 55 crosses the Minnesota River via the Mendota Bridge, which was the longest continuous bridge made of poured concrete when it was completed in 1926. It is 4,119 feet (1,255 m) in length. The Mendota Bridge between Fort Snelling and Mendota Heights carries Highway 55 over the Minnesota River. The route enters Mendota Heights and has a junction with State Highways 13 and 110.


Highway 55 continues southeast through Eagan, joining briefly with State Highway 149. The route then has a junction with State Highway 3 in Inver Grove Heights. Highway 55 then runs concurrent with U.S. Highway 52 through Inver Grove Heights and into Rosemount. At Rosemount, Highway 55 leaves U.S. 52. Highway 55 continues independently again to its eastern terminus at its intersection with U.S. Highway 61 in the city of Hastings.

Highway 110 served as an east–west arterial route between Mendota Heights, Mendota, West St. Paul, Sunfish Lake, and Inver Grove Heights. The route was a four lane divided highway with a total of seven stoplights for eastbound traffic and six westbound.

The highway had a major junction with Interstate 35E in the center of Mendota Heights. The route also has an interchange with Robert Street / Robert Trail (State Highway 3) in Inver Grove Heights.
