AS LISTED ON ROADWAY ENGINEERING'S WEB PAGE UNDER
ROADSIDE SAFETY DEVICES FOR APPROVED GUARDRAIL END
TREATMENTS. INSTALLATION SHALL BE AT THE LOCATIONS
SPECIFIED IN THE PLANS, IN ACCORDANCE WITH THE
MANUFACTURER'S SPECIFICATIONS.

REFER TO THE MANUFACTURER'S INSTRUCTIONS REGARDING
THE INSTALLATION OF, AND THE GRADING AROUND, THE
FOUNDATION TUBES AND GROUND STRUT. THE TOP OF ANY
FOUNDATION TUBE SHOULD BE LESS THAN 4 INCHES ABOVE THE
GROUND. THE PLACEMENT OF THE FOUNDATION TUBES SHOULD

AND MATERIALS NECESSARY TO CONSTRUCT A COMPLETE
AND FUNCTIONAL ANCHOR ASSEMBLY SYSTEM, INCLUDING
REFLECTIVE SHEETING AND ALL RELATED HARDWARE, GRADING,
EMBANKMENT AND EXCAVATION NOT SEPARATELY SPECIFIED,
AS REQUIRED BY THE MANUFACTURER.~~

Designer Note:
1. The length of need (LON) point is at post number 3; therefore, after calculating
the required LON for the guardrail, deduct the last 25'-0" of the unit (from post
#3 to post #9) from the length of need for the guardrail. The designer should
show the LON point on all guardrail runs in the plans.

2. Pre-approved shop drawings are reviewed and are on the Office of Roadway
Engineering's web page under Roadside Safety Devices.

3. These end treatments are gating systems.

4. The standard offset at post #1 for the B is 4'-0". This offset can be reduced to a
minimum of 3'-0" at locations where the 4'-0" offset is impractical.

5. Use this plan note in conjunction with Type MGS Guardrail.~~

GRADING, EMBANKMENT AND EXCAVATION NOT SEPARATELY
SPECIFIED, AS REQUIRED BY THE MANUFACTURER.~~

Designer Note:
1. The length of need (LON) point for both systems is at post number 3; therefore,
after calculating the required LON for the guardrail, deduct the last 37'-6" of the
unit (from post #3 to post #9) from the length of need for the guardrail. The
designer should show the LON point on all guardrail runs in the plans.

2. Pre-approved shop drawings are reviewed and are on the Office of Roadway
Engineering's web page under Roadside Safety Devices.

3. These end treatments are gating systems.

4. A Type C delineator should be installed on a flexible post at the head of all Type
E units located on the right side of the through roadway in areas that have known
snowdrift/piling problems, or per District policy. A Type D delineator should be

ITEM 606 - CABLE GUARDRAIL^^

THIS ITEM SHALL CONSIST OF FURNISHING AND INSTALLING ANY
ONE OF THE HIGH TENSION FOUR CABLE GUARDRAIL SYSTEMS
AS LISTED ON THE OFFICE OF ROADWAY ENGINEERING'S WEB
PAGE. PAYMENT FOR THE ABOVE WORK SHALL BE MADE AT THE
UNIT PRICE BID FOR ITEM 606, CABLE BARRIER WITH CONCRETE
LINE POST FOUNDATION, AND ITEM 606 CABLE BARRIER, ANCHOR
ASSEMBLY AND SHALL INCLUDE ALL LABOR, TOOLS, EQUIPMENT
AND MATERIALS NECESSARY TO CONSTRUCT A COMPLETE AND

SEPARATELY SPECIFIED, AS REQUIRED BY THE MANUFACTURER.
THE LENGTH OF THE TENSIONED CABLE NECESSARY TO INSTALL
A FUNCTIONAL ANCHOR SYSTEM SHALL BE INCLUDED IN ITEM 606,
CABLE BARRIER WITH CONCRETE LINE POST FOUNDATION.

INSTALLATION SHALL BE AT THE LOCATIONS SPECIFIED IN THE
PLANS, IN ACCORDANCE WITH THE MANUFACTURER'S
SPECIFICATIONS.

SYSTEMS SHALL HAVE A MAXIMUM DEFLECTION OF 8 FEET AND
THE MAXIMUM LONGITUDINAL DISTANCE BETWEEN POSTS SHALL
BE 15 FEET.

INSTALLATION WILL BE A FOUR CABLE HIGH TENSION SYSTEM
INSTALLED IN SOCKETED POSTS FOUNDATION WITH A FOUR FOOT
WIDE "NO MOW STRIP".

DELINEATE THE CABLE BARRIER USING TYPE 6 BARRIER
REFLECTORS PER ITEM 626 OR USING FLEXIBLE POSTS PER
ITEM 620 AS CALLED FOR IN THE PLANS OR DIRECTED BY THE
ENGINEER.

ANCHOR TERMINAL STRUTS SHALL BE COVERED COMPLETELY ON
BOTH SIDES WITH YELLOW TYPE J, ASTM D 4956 TYPE XI
REFLECTIVE SHEETING, PER CMS 730.193.

TRANSITIONS TO W-BEAM GUARDRAIL ARE NOT ALLOWED.

REFER TO MANUFACTURER FOR MAXIMUM OFFSET FROM BREAK
POINT.

TORPEDO OR BULLET SPLICES ARE NOT ALLOWED. ALL CABLE
SPLICES SHALL BE A SWAGED OR OPEN BODY DESIGN THAT
ALLOWS FOR ANNUAL INSPECTION BETWEEN THE WEDGE AND
STRANDS OF CABLE.

POSTS ARE SET IN SOCKETED CONCRETE FOUNDATIONS AND
SHALL NOT BE PERMANENTLY INSTALLED UNTIL THEIR
RESPECTIVE RUNS OF TENSIONED CABLE GUARDRAIL ARE READY
FOR FINAL CONNECTION TO THE END TERMINAL ASSEMBLY. THE
CONTRACTOR SHALL REPLACE ANY POSTS DAMAGED DURING
INSTALLATION AS DETERMINED BY THE ENGINEER AT NO
ADDITIONAL COST TO THE STATE.~~

Designer Note:
High tension cable barrier systems shall only be installed to meet the requirements of
Location and Design Manual Section 601.2 Median Barrier Warrants.

The most current approved products and models are updated regularly online, as such,
individual products should generally not be listed on the plans.

Cable barrier should be delineated using Type 6 Barrier Reflectors per Item 626 or using
flexible posts per Item 620 and the delineation should be itemized and paid for under its
respective item number.

Designer should look at the entire corridor before selecting which side of the median the
cable will be installed on. At breaks in the runs of cable such as turnarounds the layout
of the cable should limit the gating potential of the cable end treatments. Installing the
end treatments behind the trailing bridge parapets can eliminate the gating part of the end
treatments. When overlapping cable runs eliminate all of the gating part of the end
treatments. Review Figure 602-3 and 602-4 of L&D Vol. 1 for appropriate layouts.
Additional information is provided in Location and Design Manual Volume 1 Section 600 and
the manufacturer.
