VDOT has recently launched their “Corridor Wide Materials Estimate” feature on their Improve 81 website. This webpage provides estimates for asphalt, aggregates, pipe, guardrail, and structures products. The page also breaks out the estimated materials by year and by district along the I-81 corridor.
Please be sure to note the qualifiers for the materials estimates.
