Duration Chart

Lane Closure System duration field
Type Description
Standard are closures for which the lanes are closed and reopened at the same times on each day of the closure period. (e.g., lanes are closed from 1pm to 3pm every day from start-date to end-date).
Long Term are closures for which the lanes are closed continuously (24 hours/day) from the beginning of the closure period until the end (or indefinitely: only Long Term closures can have indefinite end dates).
Intermittent are closures for which some subset (possibly all) of the affected lanes are closed and reopened intermittently at unscheduled times during the closure period (usually because they have to close lanes during those brief periods when large equipment must be moved).
