MaineDOT Asset Management - Highways

Below is MaineDOT's methodology to provide a fair, structured framework to prioritize programs and projects. There are two parts - the Highway Corridor Priority (HCP), and the Customer Service Level (CSL).

See the glossary for the descriptions of each level in the priorities.

This data is available for viewing in the MaineDOT Map Viewer. Go to our " Search Map by Town" page to view maps by town.

    Summary

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 1873 8% 40% The Interstate and all other National Hwy System corridors, such as Brewer-Calais Rte 9, Newport-Gilead Rte 2, Houlton-Madawaska Rte 1
Priority 1 Highway
Priority 2 1251 5% 18% High-priority, non-NHS such as Caribou-Ft. Kent Rte 161, Bangor-Greenville Rte 15, Ellsworth-Eastport Rte 1, Farmington to Rangeley Rte 4 Priority 2 Highway
Priority 3 1257 5% 12% China-Hampden Rte 202, Cornish-Fryburg Rte 5, Lincoln-Topsfield Rte 6, Baileyville to Houlton Rte 1 Priority 3 Highway
Priority 4 4670 20% 17% Major/Minor Collectors not included above (including 3 miles of marine highway) Priority 4 Highway
Priority 5 14446 61% 13% Local Roads & Streets Priority 6 Highway
* Data based on 2021 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 information below lists the individual measures that make up the overall service level grade. To view this data in our map viewer, click on a header below.

Highway Corridor Priority and Customer Service levels are overlaid to show an aggregated state-wide view of the different priority roads with their corresponding service levels. Percentages do not reflect highway assets not managed by MaineDOT.
