Although roundabouts have recently gained popularity and use in the United States, minimal guidance is available for constructing roundabouts or installing, maintaining, and removing temporary traffic control devices in work zones where roundabouts are constructed. These guidelines provide considerations and typical applications to assist field staff in setting up temporary traffic control for both new construction and maintenance activities. The traffic control guidelines outlined in this document can be used during various maintenance and construction activities such as pavement repair, striping, signing, delineation, landscaping, and intersection repair as well as during the construction of new roundabouts.
Specifically, the guidelines give information related to:
- Temporary Traffic Control Guidance Applicable for Construction of Roundabouts
a) With all of the traffic diverted away from the work area;
b) With some of the traffic diverted; or
c) Under full traffic.
- Temporary Traffic Control Guidance Applicable for Existing Single-lane and Multi-lane Roundabouts
a) Single-Lane Roundabouts with partial closure;
b) Single-Lane Roundabouts with Partial Closure with Detour;
c) Multi-Lane Roundabouts with Inside Lane Closure; and
d) Multi-Lane Roundabouts with Outside Lane Closure.
