Traffic Control Through Construction FAQs
|
| |
| QUESTION 1 |
I've seen signs which
say "Fines Double in Work Zones" in some work zones, but not
in others. Does the double fine only apply where the signs are posted?
|
| |
| Answer: |
No, the law applies in all work zones. Signs are posted on
larger projects as a reminder to the traveling public. |
| |
| QUESTION 2 |
I went through a work
zone on a divided highway where all the traffic was carried on one side
while they were working on the other side. Some of the tubular markers
separating the traffic had been hit and were in the middle of the road.
Why don't they just take them out? |
| |
| Answer: |
The nationwide guideline, the Manual on Uniform Traffic Control
Devices, states "When traffic control must be maintained on one roadway
of a normally divided highway, opposing traffic shall be separated either
with portable barriers (concrete safety-shape or approved alternate),
or with channelizing devices throughout the length of the two-way operation.
The use of striping, raised pavement markers, and complementary signing,
either alone or in combination is not considered acceptable for separation
purposes." |

| QUESTION 3 |
What is the difference
between "Road Closed" signs and "Road Closed to Thru Traffic"
or "Road Closed ** Miles Ahead Local Traffic Only" signs? |
| |
| Answer: |
If the sign says "Road Closed", only authorized
vehicles may be in the work area. The other two signs are used where through
traffic must detour around the work area; local traffic accessing businesses
or residences within the work area may enter the work area. "Road
Closed to Thru Traffic" is used where the actual road closure is
less than a mile from the sign, whereas the latter sign is used where
the distance to the closure is two or more miles away. |

| QUESTION 4 |
What does "Uneven
Lanes" mean? |
| |
| Answer: |
The Uneven Lanes sign is used where there is a difference
in height between adjacent lanes of traffic |
