DP Road Phase II Reconstruction Project Update
TLC Plumbing & Utility is in its initial ramp-up, and businesses and visitors will progressively see construction activity increase in the area. Parking restrictions are in place along the south side of DP Road. TLC is currently performing potholing of existing utilities in this area along the south side of DP Road and is also in the process of creating new parking just south of the ACE Hardware Store. Once the parking area is complete it will be available for parking to the public. This is anticipated within the next week.
Currently, Los Alamos County has opened up an additional temporary parking area within the Los Alamos County parcel directly across and south of the Los Alamos Fire Training Academy. This area is available to the public.
Work zone traffic control will be commencing soon. This will include a lane shift eastbound on DP Road from the Fire Academy property along the work zone to CrossFit Los Alamos Gym. Once traffic control is placed, please follow all work zone signs and exercise caution around the work zone. Flaggers may also be present to direct traffic during certain construction events, both east and westbound. Access to businesses will be maintained, and westbound traffic from the TA-21 gate to the beginning of the project will be in its current alignment at this time.
Services such as mail delivery, trash and recycling collection, and emergency services will be maintained. Businesses can expect large equipment, and construction noise.
