Project Information

This project added 12-foot continuous truck climbing lane to southbound Interstate 81 from milepost 120 near Christiansburg to milepost 125. 

The project included the upgrade of the median and outside shoulder of I-81.  The southbound bridge over the railroad tracks were replaced to incorporate one additional lane and increase the shoulder width to meet current interstate standards. Route 636 (Seneca Hollow Road and Friendship Road) are two-lane roadways that cross over I-81 twice, once atmile marker 123 and once at mile marker 124.9.  These two bridges were reconstructed to allow for the additional lane.

The total estimated cost for a truck climbing lane on southbound Interstate 81 from mile marker 120 to mile marker 125 is $75.4 million.

No businesses, residences or non-profit organizations were displaced as a result of this project.

Benefits

Completion of the project enhanced the safety of I-81 in this area by allowing slower moving vehicles to stay in the right two-lanes. Other benefits of the project include better traffic management with wider shoulders plus the use of the additional travel lane during traffic incidents.
