Highway construction costs vary from state to state, but the average cost per mile of highway is $8 million. The average cost of concrete pavement is $10,000 per lane mile and asphalt pavement is $7,000 per lane mile.
The cost of building a highway depends on many factors, including the type of road being built and where it will be located.

The best way to estimate the costs associated with building highways is to consult an engineer or contractor who specializes in road construction and to get estimates from several companies if possible.
Cost to build a highway
The average cost to build a highway is $3.5 million per mile, according to the Federal Highway Administration. This cost includes design, construction, right-of-way acquisition and other associated costs.
The cost to build a road varies widely depending on the type of road being built and where the road is located. For example, building an interstate highway can cost as much as $25 million per mile while building a rural highway only costs about $2 million per mile.
Costs also vary widely depending on what region of the country you are in as well as whether your state or local government is footing the bill or if it will be funded with federal dollars.
Road Construction Costs Per Mile
According to the Federal Highway Administration (FHWA), the average cost to build a road ranges from $1 million per mile for urban roads up to $6 million per mile for rural interstates.(1) The FHWA reports that most major highways cost between $2-4 million per mile.(2)
These numbers represent averages across all types and sizes of highways including interstates, freeways and arterial roads. In addition, these numbers do not include maintenance costs for highways which would increase these totals significantly over time due to wear and tear caused by weather conditions.
