Construction Work in Dover and Rochester on the Spaulding Turnpike

Lane closures and lane shifts will be utilized throughout the summer.

The New Hampshire Department of Transportation (NHDOT) has begun construction work to replace the toll booths on the Spaulding Turnpike (Route 16) in Dover and Rochester, NH. Over the next two summers an All Electronic Tolling (AET) system will be built and the existing toll booths will be removed. 

Temporary portable concrete barriers have been installed in Dover and Rochester on the median side of the northbound and southbound barrels near the existing toll plazas and traffic has been shifted into the low speed shoulder to allow for the upcoming reconstruction of the median.  These shifts will be in place for approximately three months.  In conjunction with these shifts, temporary lane closures will be used as needed. 

The work in the median will include the construction of new drainage systems, the construction of roadway select materials and pavement to replace the existing median, and the construction of permanent concrete barrier thru the area. 

In addition to the work in the median, construction of the foundations for the AET Gantries (overhead support structure with traffic monitoring equipment) will also be completed as part of this phase.  This work will be on the outside of the northbound and southbound barrels approximately 600 feet north of the existing Toll Plazas.  Temporary portable concrete barrier will be installed on the outside of the travel area to facilitate this work.
