New storm water drainage system under the M1

Roads and Maritime Services have begun a $2.5 million upgrade on the M1 Pacific Motorway at Somersby to improve drainage capacity and motorist safety during wet weather.

Member for Gosford Mr Chris Holstein said work was being carried out north of Gindurra Rd to provide a new storm water drainage system under the M1 to reduce the impact of storm water on motorists. “The project will increase safety for all road users, particularly during wet weather,” Mr Holstein said. “The project will require vegetation clearing on the central median, which will be reseeded to allow for new vegetation growth.

Work will be carried out in three stages to minimise the impact on traffic along the M1. The first stage of work to install the stormwater pipe under the roadway began on Monday, May 19, between 7am and 5pm and is expected to take two weeks to complete. Night work will be carried out in early June to install a stormwater pipe under the central median. This work will take place Sunday to Thursday between 7pm and 4am and is expected to take five weeks to complete. The final stage of work involves installing storm water outlets and is expected to start in mid-July.

This part of the project will take around two months to complete, weather permitting. Additional night work may be required and the community will be notified of this before work starts.
Changed traffic conditions will be in place during work including reduced speed limits and lane closures.
