The Waitangi Bridge at Awatoto on SH2 will be closed to night traffic from next Monday as contractors carry out the installation of piles for a future clip-on cycle way.
The bridge will close between 7pm through to 6.30am as pile-driving equipment will need to be placed across the roadway.
The work is expected to be wrapped up by April 25.
A spokesperson for Opus International said there would be no impact of motorists commuting between Napier and Hastings between 6.30am and 7pm, although people planning to travel between the twin cities at night need to plan their route.
Detour signage will be in place on Awatoto Rd, Meeanee Rd, the SH50 Expressway, Pakowhai Rd and Farndon Rd and night drivers have been advised travel times will accordingly be longer.
