PROVIDENCE, R.I. (AP) — Federal and state officials in Rhode Island are holding a groundbreaking on a major project to replace two bridges that run through the middle of Providence.

Two new spans will be built to replace the deteriorating bridges of the Providence Viaduct, and the old ones will eventually be torn down.

The work is expected to cost nearly $150 million and stretch into late 2018. The state will pay 20 percent of the cost, with federal money being used for the rest.

State Transportation Director Michael Lewis says the replacement of the Viaduct is critical and that the quality of a state's infrastructure is directly linked to the economy.

The groundbreaking is scheduled for Monday morning. Members of Rhode Island's congressional delegation and Gov. Lincoln Chafee are expected to attend.
