8.2. Infrastructure Improvement Cost Opinions
This section presents planning-level cost opinions for the comprehensive network of on-street bikeways and
multi-use paths recommended in the Greenville Bicycle Master Plan. Cost estimates for bikeway facilities are
based on cost opinions provided by the City of Greenville. The cost of bikeway facilities significantly varies by
facility type, as shown in Table 8.2-1. For example, the addition of shared lane marking (sharrows) to an
existing roadway requires few changes to the existing roadway, but provides no exclusive space for bicycle
use. By contrast, a separated multi-use path provides a far greater level of separation from the roadway, but at
a greater fiscal burden. The following is a summary of the fully burdened costs of different bikeway facility
types and their associated costs. All costs are total installed costs that include: planning and engineering,
environmental, and contingency.
Facility Cost Materials
Multi-use path (per mile) $ 800,000.00
Bike lanes: restriping (per mile) -
