Telephone Survey Solutions did not differ significantly for those living inside or outside the Beltway. Stakeholders believe I-66 I is becoming more congested. 47% of commuters rated bus / rail transit as their first choice to reduce congestion. 52% suggested road widening as a solution. 57% say doing nothing is the least popular solution.
