FARMINGTON — A traffic jam clogged Main Street near 20th Street Wednesday morning following road construction that shut down all but the outermost lanes in both directions. The construction is part of a Department of Public Works project to resurface portions of the Main Street corridor before winter conditions make paving impossible. “Main Street was on the resurfacing list,” said City Engineer Nica Westerling. “It’s been about 10 to 15 years since it was last done.” The project is divided in to two stages: 20th to 30th Streets and 30th Street to English Road. The city employed Cutler Repaving, which has a statewide contract for repaving services. They use a technique known as curbline milling to tear out the top inch and a half of asphalt. Construction between the streets is expected to last until Oct. 20, said Davis Gonzales, project superintendent. Pavers began laying new asphalt around 8:30 a.m. The heavy machinery will further complicate traffic conditions in the area, Gonzales said. Motorists are advised to seek alternate routes, especially during morning and evening rush hours. For more information, call the Department at Public Works at 505-599-1308.
