The final phase of the three-year, $99.7 million construction project to add an additional travel lane in each direction between Thruway exits 23 and 24 is scheduled to begin this month, the Thruway Authority announced today.
Effective March 12, northbound traffic will be diverted across the median near exit 23 to continue north on the newly constructed southbound roadway. Two lanes will remain open in both directions throughout this last phase of the project.
Northbound and southbound traffic will be separated by concrete barriers, which will begin to be put in place by construction crews today.
These dates are subject to change in the case of inclement weather.
Work to be done this year on the northbound side includes the addition of a third travel lane, the installation of new pavement, addition of a variable message sign, and noise barriers, as well as the completion of drainage work and the painting of three overhead bridges.
When construction ended for the season in November 2012, the new southbound roadway was laid out with two lanes already configured as needed for the final phase of the project.
According to the Thruway Authority, configuring the southbound lanes last fall in preparation for this year saved about $70,000 in construction-related costs. Eliminating the need to relocate overhead signs for the final construction phase will mean additional savings.
Work on the project began in March 2011 and is scheduled to be completed in the fall of 2013. The general contractor is Rifenburg Construction Inc. of Troy.
