CLEAR ZONE WIDTHS FOR WORK ZONES:
<br />The term 'clear zone' describes the unobstructed relatively flat area, impacted -
<br />by construction, extending outward from the edge of the traffic lane. The
<br />table below gives clear zone widths in work zones for medians and roadside
<br />conditions other than for roadside canals; where roadside canals are present,
<br />clear zone widths are to conform with the distances to canals as described in
<br />the FOOT Design Manual 215.2.
<br />SUPERELEVATiON:
<br />Horizontal curves constructed in conjunction with work zone traffic
<br />control should have the required superelevalion applied to the design
<br />radii. Under conditions where normal crown controls curvature,
<br />the minimum radii that can be applied are listed in the table below.

<br />LENGTH OF LANE CLOSURES:
<br />For interstates and state highways with a posted speed of
<br />55MPH or greater, lane closures must not exceed 3 miles
<br />(includes taper, buffer, and work zone) In any given direction
<br />and must not close two consecutive interchanges.

<br />OVERWEIGHT/OVERSIZE VEHICLES:
<br />Restrictions to Lane Widths, Heights or Load Capacity can
<br />greatly Impact the movement of over dimensioned loads. The
<br />Contractor shall notify the Engineer who In turn shall notify the
<br />State Permits Office, phone no. (850) 410-5777, at least seven
<br />calendar days in advance of implementing a maintenance of
<br />traffic plan which will impact the flow of overweight/oversized
<br />vehicles. Information provided shall include location, type of
<br />restriction (height, width or weight) and restriction time frames.
<br />When the roadway is restored to normal service the State
<br />Permits Office shall be notified immediately.
<br />LANE WIDTHS:
<br />Lane widths of through roadways should be maintained through work
<br />zone travel ways wherever practical. Provide minimum widths for
<br />work zone travel lanes as follows: 11' for Interstate with at least
<br />one 17 lane provided in each direction, unless formally excepted by
<br />the Federal Highway Administration; 11' for all other limited access
<br />roadways; and Id for all other facilities.
<br />HIGH -VISIBILITY SAFETY APPAREL:
<br />All high -visibility safety apparel shall meet the requirements of the International
<br />Safety Equipment Association (ISEA) and the American National Standards Institute
<br />(ANSI) for "High -Visibility Safety Apparel", and labeled as ANSIIISEA 107-2015 or
<br />newer. The apparel background (outer) material color shall be either fluorescent
<br />orange -red or fluorescent yellow -green as defined by the standard. The
<br />retroreflective material shall be orange, yellow, white, silver, yellow -green, or a
<br />fluorescent version of these colors, and shall be visible at a minimum distance of
<br />1,000 feel. Class 3 apparel may be substituted for Class 2 apparel. Replace
<br />apparel that is not visible at 1,000 feet.
<br />WORKERS: All workers within the right-of-way shall wear ANSI/ISEA Class 7
<br />apparel. Workers operating machinery or equipment in which loose clothing could
<br />become entangled during operation shall wear fitted high -visibility safety apparel.
<br />Workers inside the bucket of a bucket truck are not required to wear high -visibility
<br />safety apparel.
<br />UTILITIES: When other industry apparel safety standards require utility workers to
<br />wear apparel that is inconsistent with FOOT requirements such as NFPA, OSHA, ANSI,
<br />etc., the other standards for apparel may prevail.
<br />FLAGGERS: For daytime activities, Flaggers shall wear ANSI/ISEA Class 2 apparel.
<br />For nighttime activities, Flaggers shall wear ANSI/ISEA Class 3 apparel.
