102-GEN-NOTES

103-GEN-SIGN

104-GEN-AB

105-GEN-SPEED-FW

The Contractor shall not create any unsafe conditions within the Construction Influence Area (CIA) that form a hazard for motorists. Extra caution should be used when delineating the work zone overnight to protect the roadway users.

No work shall be performed, or lane closures allowed during the Memorial Day holiday, Independence Day or Labor Day holiday period. The Memorial Day holiday period shall be defined as beginning Thursday, May 23, 2024, at 6:00 pm until Tuesday, May 28, 2024, at normal starting time.
