- Cost to convert two reversible high-occupancy
vehicle lanes on an eight-mile stretch of the Interstate-
15 in San Diego to high-occupancy toll lanes was
$1.85 million.
- Cost estimates of operational concepts for
converting HOV lanes to managed lanes on I-75/I-575
in Georgia range from $20.9 million to $23.7 million
Notes:
* Overall Cost Range applies to the application of a treatment in roadway segment or corridor. For example, several DMS can be installed along a important
route.
**Unit costs were found by adding the unit cost of different equipment for each treatment. This methodology does not apply to all treatments (e.g., TMC,
Integrated Multimodal Corridors, etc.)
