MaineDOT Asset Management - Highways

Highway Corridor Priority (HCP)

The first part of the method, the Highway Corridor Priority (HCP), categorizes our highway assets into six levels of priorities.

Highway Corridor Priority	Miles	% Miles	% Traffic	Example (click on thumbnail to view image)
Priority 1	1730	7 %	41 %	The Interstate, Brewer-Calais Rte 9, Newport-Gilead Rte 2, Houlton-Madawaska Rte 1
Priority 2	960	4 %	12 %	The National Hwy System, Caribou-Ft. Kent Rte 161, Bangor-Greenville Rte 15, Ellsworth-Eastport Rte 1, Lewiston-Bethel Rte 11/26
Priority 3	1980	8 %	17 %	Manchester-Farmington Rte 17, Saco-Fryburg Rte 5, Lincoln-Vanceboro Rte 6, Sherman-Ft. Kent Rte 11
Priority 4	1970	8 %	9 %	Major Collectors not included above
Priority 5	2480	11 %	8 %	Minor Collectors not included above

* Data based on 2010 asset inventory

Customer Service Level (CSL)

The second part of the method is determining the Customer Service Level (CSL) that measures MaineDOT managed highway assets (Priority 1-5) in three areas. The CSL uses customer-focused engineering measures to track highway (1) Safety, (2) Condition and (3) Serviceability, and grades them similar to a report card (A – F). The table below lists the individual measures that make up the overall service level grade.
