The Tricounty Bridge was supposed to relieve traffic in East Countway County. Although the bridge was opened last year, traffic in the county has gotten worse over the last year. To relieve the traffic situation in East Countway, therefore, the traffic commission should order the Tricounty Bridge closed.　 Which of the following, if true, gives the most support to the conclusion of the passage above?
A

The increased traffic seen in East Countway over the last year is largely attributable to a large casino and resort hotel that opened for business shortly after the opening of the Tricounty Bridge.

B

The Tricounty Bridge allows inhabitants of heavily populated West Countway County to reach East Countway in less than a half-hour, as opposed to the two hours the trip required before the opening of the bridge.

C

The bridge is only open for the periods 7-9 a. m. and 3-5 p.m. on weekdays.

D

Ship captains on the Countway River have complained that the bridge disrupts shipping on the river, thereby hurting the local economy.

E

The bridge is unlikely ever to pay for itself with the current low toll payment.
