In 2011, the city DOT
spent $2 million dollars
to fill additional potholes.
That’s more than it spent
out of its own budget
over THREE years for its
bicycle program.

"When we talk about „Complete Streets,‟ we aren‟t
necessarily talking about expensive widening
projects or major redesigns of our roadways. These
concepts can often be applied to existing streets by
simply re-thinking how we approach traffic flow and
how we accommodate all modes of transportation.”
– Phil Broyles, Director of Public Works, Springfield, Missouri

Complete streets can save money.
• Narrower travel lanes require less land, less
pavement
• Provide more options = reduce need for
widening some intersections
• Do it right the first time, not when forced to
later—at a higher price

“Implementation of Complete Streets goals
can actually keep costs at acceptable levels
and save money, while adding more public
benefits and return on investment.”

"The [Complete Streets] processes that we are
going through now in project development
should lead to fewer changes in construction
by addressing the issues upfront. If you are
properly going through the project
development process, you should have lower
costs, fewer change orders, and fewer delays
because people are not coming out during the
construction phase to demand changes.”
– Thomas DiPaolo, assistant chief engineer for MassDOT

“This [Complete Streets policy] puts the framework in place
that allows the city to start with a project in the design
phase and include these multi-modal recommendations. It
will be at a much lower cost than tearing up something
that‟s already in place.”

Notes de l'éditeur
In implementing Complete Streets, Charlotte has found that project costs vary greatly by adjoining land use, terrain, and the need to purchase right-of-way. For example, the city runs a program to improve rural, farm-to-market roads to serve new development, which can include installation of curbs and gutters, stormwater drainage, roundabouts, turn lanes, medians, bicycle lanes, sidewalks, and other necessary infrastructure. Such projects can cost as little as $6 million per mile or double that. New arterials can cost the city $5 million per mile or up to twice that amount. The costs that can be attributed to Complete Streets features on these projects are relatively small, 4–8 percent of total project costs, but add high value and are simply part of the highly variable mix of project costs.
