For an everyday main street say 「大通り」; for the busiest shopping street, 「目抜き通り」. 「大道」 leans written and often means the moral path, as in 「人の大道を歩む」, or appears in 「大道芸」. 「本通り」 is an everyday word for a town's main street, also common in place names; 「広小路」 and 「ブールバード」 show up mostly in place or street names, and 「大路」 is archaic. Opposites: 「小道」, 「脇道」.
