State Route 89 (SR 89) is part of Maine's system of numbered state highways. It runs 10.87 miles (17.49 km) from an intersection with SR 161B and SR 164 in Caribou to an intersection with U.S. Route 1A (US 1A) in Limestone. The route is also known as Access Highway (in Caribou) and Foster Avenue (in Limestone).
The road was designated as a service route for the now defunct Loring Air Force Base.
SR 89 begins at a right-in/right-out intersection with Main Street in downtown Caribou. Main Street in this area carries the northbound lanes of SR 161B and the southbound lanes of SR 164. SR 89 heads east along the two-lane High Street passing numerous businesses and residences. At the intersection with US 1 and SR 161, SR 89 turns north onto the divided four-lane highway. First SR 161 exits the road onto a bypass of the city while US 1 exits the highway later on. Now named Access Highway, the road becomes undivided and two-lanes wide. It first passes businesses on its north side and small houses on the south side. After passing under the SR 161 expressway and a recreational trail paralleling the bypass, SR 89 heads northeast through a more rural area. At the settlement of Madawaska, the highway reaches the western terminus of SR 223 and crosses the Little Madawaska River.
