Road or highway 路 United States

How much did the four-lane widening of US 550 (former NM 44) in New Mexico cost?

U.S. Route 550 runs from Bernalillo, New Mexico, to Montrose, Colorado, and its Colorado stretch is the scenic Million Dollar Highway. The biggest documented project on it is the widening of the former NM 44 in northwest New Mexico from two lanes to a four-lane divided highway between San Ysidro and Bloomfield, about 118 miles, designed from 1998, built from 1999 and finished in 2001, after which the road was renamed US 550. The total expenditure was USD 345 million according to a 2008 Albuquerque Journal study report; other accounts give USD 300 or 312 million.
