WHITE RIVER JUNCTION, Vt. (AP) The Vermont Transportation Agency is using what it calls a “slide-in construction technique’’ to minimize disruption for travelers when it replaces two Interstate 91 bridges in White River Junction.

The highway will remain open during construction except for two weekends, probably in late August.

On those two weekends, the road will be closed in one direction and traffic detoured while an existing bridge is rapidly demolished and a new bridge is slid into place.

Deputy Transportation Secretary Chris Cole said the two bridges are near the interchange with Interstate 89 so it is essential to minimize the time the bridges are closed.

“Deploying this innovative construction technique is another example of our commitment to maintaining mobility while being good stewards of our interstate highway system,’’ Cole said.

The two new bridges will be built on temporary supports next to the bridges they are replacing this spring and summer. The foundations for the new bridges will be built under the existing bridges. The new bridges will be slid into place when they are done.

The new bridges are slated to be installed in August.

The slide will take place over two consecutive summer weekends, one bridge on each weekend. The tentative schedule for installing the new bridges is the last two weekends in August. The alternative dates are in mid-September.
