 a freeway ( 20 );   a second freeway ( 280 );   a west east bound off ramp ( 120 ) extending from said west bound freeway lane ( 250 ) to the circular road ( 40 ) and then to a north bound on ramp ( 160 ), said north bound on ramp ( 160 ) extending to a north bound freeway lane ( 290 );   an east bound off ramp ( 140 ) extending from an east bound freeway lane ( 240 ) to the circular road ( 40 ) and then to a south bound on ramp ( 180 ), said south bound on ramp ( 180 ) extending to a south bound freeway lane ( 300 );   a south bound off ramp ( 170 ) extending from a south bound freeway lane ( 300 ) to the circular road ( 40 ) and then to a west bound on ramp ( 130 ), said west bound on ramp ( 130 ) extending to a west bound freeway lane ( 250 );   a north bound off ramp ( 190 ) extending from a north bound freeway lane ( 290 ) to the circular road ( 40 ) and then to an east bound on ramp ( 150 ), said east bound on ramp ( 130 ) extending to an east bound freeway lane ( 240 );   a circular road ( 40 ) connecting said west bound off ramp ( 120 ) to said north bound on ramp ( 160 );   said circular road ( 40 ) connecting said east bound off ramp ( 140 ) to said south bound on ramp ( 130 );   said circular road ( 40 ) connecting said south bound off ramp ( 170 ) to said west bound on ramp ( 130 ); and   said circular road ( 40 ) connecting said north bound off ramp ( 190 ) to said east bound on ramp ( 150 ).   
     
     
         7 . The apparatus of  claim 6 , further comprising:
 a first bypass ( 310 ) from said west bound freeway lane ( 250 ) to a north bound freeway lane ( 290 );   a second bypass ( 320 ) from said south bound freeway lane ( 300 ) to a west bound freeway lane ( 250 );   a third bypass ( 330 ) extending from said east bound freeway lane ( 240 ) to a south bound freeway lane ( 300 ); and   a fourth bypass ( 340 ) extending from said north bound freeway lane ( 290 ) to an east bound freeway lane ( 240 ).   
     
     
         8 . The apparatus of  claim 6 , wherein at least one of either said first bypass ( 310 ), said second bypass ( 320 ), said third bypass ( 330 ) or said fourth bypass ( 340 ) is disposed inwardly of said circular road ( 40 ).
