The Waitangi Bridge on SH2 at Awatoto will be closed to night traffic for about a week to allow contractors to install a section of cycleway as part of a new section being built between it and the Ngaruroro Bridge.
Contractors have been at work for the past few weeks and, while there were no traffic delays created, the highway shoulder had been closed off.
New Zealand Transport Agency journey manager for Napier Oliver Postings said the date for the night closures was still to be set but it would be about mid-June.
Work on upgrading the Ahuriri Estuary Bridge on the SH2B Expressway was wrapped up last weekend.
Mr Postings said staff appreciated the patience of drivers who had experienced frustrating delays at times.
