MORRISVILLE (AP) - Vermont Gov. Peter Shumlin has signed the largest transportation bill in state history.

On Monday Shumlin signed the bill that approves $685.7 million in infrastructure improvements and maintenance.

The bill signed in Morrisville includes $115.7 million for paving, a 7 percent increase that's part of an ongoing plan to improve the condition of the state's highways and $140.3 million for bridges, up 6 percent over last year.

The governor's office says Vermont is making progress in catching up with needed maintenance.

In 2008, Vermont ranked 45th in the nation for the number of structurally deficient bridges. By 2013, the state ranked 28th. The percentage of pavement rated in very poor condition has declined from 36 percent in 2008 to 21 percent in 2013.
