North I-81 Sewer Extension Project - UPDATES

Paving contractor, BF Brown, will be doing various patching and temporary paving repairs in the North I 81 sewer project area starting on Millers Gap Road Tuesday, December 12th.  Through-out the balance of that week other areas in the White Birch Farms subdivision will also be addressed (weather permitting) and then major road base and binder reconstruction will resume in the Spring of 2024.

The paving contractor that will be doing the restoration of Old Willow Mill Park Road between Sunset Drive and the southern berm of Route 944 will be doing that work on Thursday, November 16 and Friday, November 17.

This delay is due to some equipment malfunctions that had to be corrected before returning to the work site.  The travel lanes will be restricted during this work to buses, residents that live within the work area, and emergency vehicles.

The PACT One, LLC (PACT) paving subcontractor, BF Brown (Brown), completed road base and binder pavement restoration within the Sample Bridge Estates subdivision this week.  Brown has demobilized temporarily and intends to resume work during the week of October 23rd.   

There is a possibility that the work could resume in the latter half of the week of October 15, depending on weather and availability of the paving crew.  The plan at present and upon Brown’s return, is to address restoration on Sample Bridge Road and continue onto the Sunset Drive and Old Willow Mill Road areas of work.  While working within Sunset Drive the expectation is that Sunset Drive would be closed between intersections much like PACT did during the course of the sanitary sewer installation in this area.  To avoid any issues with the traveling public and recognizing that school is in session, PACT has requested that flagging operations continue during the course of this work.

The Sewer Authority asks for your continued patience and understanding so the workers may complete the job safely and return the road to a better condition than it was before the sewer installation project began.

The PACT One schedule for commencing pipelaying operations on the northside of Wertzville Road/Rte. 944 has been revised due to recent lost workdays/wet weather.  The anticipated start date for construction activity within the Millers Gap Road area of work is July 5th, 2023, and advanced road closure/detour notification signage will reflect this new date.  In addition, pipelaying operations south of Wertzville Road and within the White Birch Farm Estates area shall be completed this week, with remaining items of work to include testing and restoration.

PACT One LLC (PACT) will have an additional pipelaying crew available for a period of approximately two weeks commencing June 5th.  PACT plans to begin pipelaying operations within the residential areas of Amity Lane/Smiley Drive during this time period. 

May 25, 2023

PACT One LLC will complete pipelaying operations along Sunset Drive by the middle of next week (June 1) and anticipates moving directly onto White Birch Avenue and Marble Street.  PACT estimates a duration of approximately 3 weeks to completion for pipelaying operations within the White Birch Farm Estates area.  Upon completion of work in these areas, PACT will immediately move to the Millers Gap Road side of the project, at which time the Millers Gap Road work will commence.  For everyone’s safety, Millers Gap Road shall remain closed between Wertzville Road and Amity Lane to allow completion of pipelaying at greater depths in this area.   Advance notice signs will be posted along Millers Gap Road on June 5th to advise of the proposed June 19th road closure and detour.

Due to inclement weather, PACT One, LLC (PACT) pipelaying operations and the Old Willow Mill Road closure with detour shall be postponed until Tuesday, March 14th weather permitting.

March 2, 2023

The utility boring subcontractor, L&N Zimmerman, moved-up their availability in terms of mobilization for the proposed roadway bore of Wertzville Road for the North I-81 Sewer Extension Project.  As a result, actual closure dates for the Old Willow Mill Road closure/detour will commence on Monday, March 13th.  Advance signage notifications advising the traveling-public of the proposed closure shall be placed March 2nd.

February 23, 2023

L&N Zimmerman has advised that mobilization for the Wertzville Road jack and bore operation for installing sewer lines under Route 944 shall commence on Monday, March 20, 2023.  PACT will post advance road closure notification signage, “This Road To Be Closed For Construction On Or About March 20, 2023”, along Old Willow Mill Road during the week of March 6, 2023. The term of the closure is estimated to be approximately 30 days.

October 21, 2022

The North I 81 Sewer Extension Project has commenced, and gravity sewers have been installed in the Wild Rose Lane and Huston Drive areas.   The contractor will be installing laterals in Wild Rose and Huston Drive over the next two weeks.  PACT One, LLC will then be moving towards the South Locust Lane, lower Pine Hill Avenue, and White Birch Lane areas over the next month, barring any unforeseen delays.  The pump station work is also underway, and the force main installation will be coming through Wild Rose Lane near the end of November.  Directional boring work to get under Interstate 81 should begin on October 24 and will be undertaken on the western sides of the Sample Bridge Road overpass.   The bore and receiving pits will be sited near the overpass and near the intersections of Wild Rose Lane and Sample Bridge Road and Rycroft Lane and Sample Bridge Road.  The directional boring work is anticipated to take about three weeks, with force main installation in parts of Sample Bridge Road and Wild Rose Lane occurring after the directional boring work under Interstate 81.  Bedrock blasting activities will be undertaken in the next two weeks in the Simmons Run hollow moving from the pump station site towards Sample Bridge Road.

September 8 Update:

PACT One, LLC (PACT) will start the North I-81 Sewer Project pipelaying operations for the Wild Rose Lane/Houston Drive areas of work next week (Sept 12-16).  Some equipment and materials will be moved into that area by the end of this week and continue through early next week.  It is our expectation that this work will have a duration of approximately 6 weeks.  An additional pipe crew will be mobilized in the week of September 26th to work within easement areas and complete the wet-well/pump station installation at the end of South Locust Lane.
