Traffic Barricade Types – What Do They Mean

Wednesday, September 18, 2013 By: admin

type2If you are in the market for traffic barricades but don’t know too much about them you have come to the right spot.  First off, the type of barricade has to do with how many boards and/or pieces of sheeting a barricade has.  Note: ‘sheeting’ is short for reflective sheeting, the orange and white striped piece you see on the barricade.  The first barricade on the left is a type 1, the second a type 2 and the third one is the type 3.

A type 1 barricade has a piece of sheeting on the top board only, and the barricade itself is usually 24″ wide and 42-46″ high (depending on if it is open or closed at the bottom).  It still has a bottom board,

but the board has no sheeting on it.  A type 2 barricade has sheeting on both the top and bottom board of the barricade.  Like the type 1 it is the same size (24″ wide and 42-26″ high).
The type 3 is a very different unit because it can range from 48″ to 144″+ in width.  As you can see there are three boards, which command a lot more attention to the unit.  These are great for road closures where you need to cover wide distances.  The sheeting is on all three of the boards typically.

What are Jersey Barriers?

jersey barrierJersey barriers are known as K-rail to the western US (California Department of Transportation came up with K-rail).  They are either concrete or plastic barrier walls used during highway construction to separate opposing lanes of traffic.  The barriers we sell are plastic water fill-able barriers.  They are easier to ship than concrete barriers because they weigh a lot less.

A typical jersey barrier is 32″ tall but lots are also 42″ tall.  The first picture to the left is a 42 x 72″ water fill-able barrier.  Jersey barriers were invented in New Jersey in the 1950’s at the Stevens Institute of Technology.  The main goal of the barrier is to prevent head on collisions from the other lane when a vehicle goes off course.

highway barrierThe official name for a 42″ tall barrier is an Ontario Tall Wall.  The Ministry of Transportation in Ontario, Canada is replacing guardrails these these taller-jersey barriers on some 400-series highways.

It is important to note that the first barrier pictured on the left is not approved for use on highways by the FHWA but the second barrier you see on the left is.  It’s called an MB350 barrier and is actually safer than a concrete barrier in a crash.  This barrier meets the TL3 compliance by FHWA when 33 barriers are interconnected in a row, and each barrier must be ballasted to equal 1,500lbs.

It’s also popular to use jersey barriers to provide some protection against possible terrorist attacks.  They have even been used in the G-20 summit to prevent protesters from getting in restricted territory.  We sell the MB350 here http://www.trans-supply.com/p-552-highway-jersey-barrier.aspx and the 42 x 72 (first one) here: http://www.trans-supply.com/p-378-42-x-72-jersey-style-lcd.aspx

Type 3 Barricades – What’s in a name?

Thursday, November 29, 2012 By: admin

Where did type 3 barricades get their name from?  Well, the number stands for the number of sheeted boards.  For example, a type 1 barricade has one board that is sheeted (though it could have two boards, since the second board isn’t sheeted it’s still considered a type 1).

A type 2 barricade can look  just like a type 1, however two of the boards would be sheeted.  The type has nothing to do with the level of sheeting.  The three is also a flat barricade where the one and two have an ‘a-frame’ shape.

type 3 barricade, type 3 barricades, traffic barricade, traffic barricades, plastic traffic barricades, plastic traffic barricadeHave you seen a type 3 barricade that is a color besides white?  I recently posted about arrow boards and the fact that I have never seen one with colors other than yellow.  When I say white, I am talking about the actual color of the boards.

There are type 3 plywood barricades out there, but from what I remember they are all painted while.  The legs, if they are steel, seem to be some sort of silver color while the plastic legs are always white.

Here are some examples of traffic barricade terms – type 1 barricade, traffic barricade, construction barricade, the list goes on and on.  Using a search tool may be the most effective way of knowing what terms are used the most.
