AMATRICE, Italy (AP) – The mayor of quake-devastated Amatrice says damage from aftershocks to two crucial access roads threatens to isolate the tiny Italian hilltop town as it struggles to dig out of the rubble.

Mayor Sergio Pirozzi said he was working with authorities to find alternative routes to bypass the damaged bridges. He says “we hope to God it works, because otherwise, with the damaged stretch of road, we are without any connection” to the main roads.

Even before the bridges were shut down Friday, traffic into and out of Amatrice was terribly congested. Emergency vehicles have been bringing scores of rescue crews up to town and dump trucks have been carrying tons of concrete, rocks and metal back out the single-lane roads.

Wednesday’s 6.2 earthquake in central Italy killed at least 267 people and left hundreds injured.
