A developer has applied for a construction permit to build a supermarket at the southeast corner of

an intersection that is formed by a four$-$lane divided highway in the east$-$west direction and a two$-$

lane road in the north$-$south direction. Traffic on the two$-$lane road is controlled by a stop sign at

the intersection. The speed limit on the four$-$lane highway is $55mph.$ Using the sight triangle

requirements at the intersection, determine whether permission should be given for the

construction if the following conditions exist.

Major road lane width $=12ft$

Minor road lane width $=11ft$

Median width $=9ft$

Design vehicle on minor road is single$-$unit truck, of which the length $=36ft$

Approach grade $=3\%$

Maximum feasible distance of building from the center of the nearest lane of the four$-$lane road

$=21ft$

Maximum feasible distance of building from the center of the nearest lane of the two$-$lane road

$=23ft$
