For this assessment, work zone projects fall into four types, which are characterized
by the levels of impact each will have on travelers:
| Type |
Characteristics |
Examples |
| Type I |
- Affects the traveling public at the metropolitan, regional,
intrastate, and possibly interstate level.
- Very high level of public interest.
- Directly affects a very large number of travelers.
- Significant user cost impacts
- Very long duration
|
- Central Artery/Tunnel in Boston, Massachusetts
- Woodrow Wilson Bridge in Maryland/Virginia/District of Columbia
- Springfield Interchange "Mixing Bowl" in Springfield, Virginia
- I-15 reconstruction in Salt Lake City, Utah.
|
| Type II |
- Affects the traveling public predominantly at the metropolitan
and regional level.
- Moderate to high level of public interest.
- Directly affects a moderate to high number of travelers.
- Moderate to high user cost impacts
- Duration is moderate to long.
|
- Major corridor reconstruction
- High impact interchange improvements
- Full closures on high volume facilities

|
| Type III |
- Affects the traveling public at the metropolitan or regional
level.
- Low to moderate level of public interest.
- Directly affects a low to moderate level of travelers.
- Low to moderate user cost impacts
- May include lane closures for a moderate duration.
|
- Repaving work on roadways and the NHS with moderate Average
Daily Traffic (ADT)

|
| Type IV |
- Affects the traveling public to a small degree.

|
These levels may not encompass all possible combinations or degrees of work zone categories. Become familiar with the work impact levels and relate them to work being accomplished in your state, regional, or local area. Some terms are general to allow you flexibility in categorizing borderline project types.
