A $4^{\text{'}}{4}^{\text{'}}$ tower is planned to be placed on the north side of a two lane rural collector roadway running east$-$west with a design speed of $55$ MPH and an ADT of $4500.$ The roadway has $12\text{'}$ lanes and a $10\text{'}$ shoulder. The south edge of the tower will be offset $4\text{'}$ from the edge of the shoulder. The west edge of the tower will be placed at station $85+45.$ The grade in the ROW outside the shoulder is at $5$:$1.$

Design the guardrail for adjacent and crossing traffic, including the starting and ending station of the guardrail.
