Project Overview

  • What work is being carried out?

The existing pipe culvert is being upgraded to a larger box culvert to reduce flood risk and to improve drainage. Excavation, culvert installation, and road reconstruction will be done using heavy machinery. Every effort will be made to minimise noise and other impacts.

  • Why is this work necessary?

The limited capacity in the existing culvert is not sufficient, contributing to flooding and road closures. The upgrade will mean more water can flow through the culvert, reducing flooding for major storm events.

  • What size will the new culvert be?

a graphic of the shape and depth of the culvert worksApproximately 2.5m wide by 1m high and will be in place around 2.5m below road level.

  • Will water, power or telecommunications services be affected?

No. There are no expected impacts to any other services.

Timing and length of works

  • Why does the work take several weeks?

The works involve large-scale excavation, installation, and reinstatement, requiring specialised equipment and sequencing.

  • Why is it being done now?

There is no ideal period that avoids all impacts, but the timing of the works balances weather conditions, flood risk, and minimising disruption to agricultural and road users.

  • Why was the start date changed?

The programme was adjusted to allow for additional communication and align with school holidays to reduce disruption.

  • What will the working hours be?

Typically work will run from 7.30am-5.30pm Monday to Friday with occastional extended hours if required.

Construction Approach

  • What will happen to the existing culvert?

The existing culvert will remain.

  • Why is a full road closure required?

It is not safe or practical to maintain traffic due to the depth and size of the excavation to install the new culvert and the limited road width.

  • Were alternative construction options considered?

Yes. Staged construction, temporary roads, and traffic management options were assessed but were not feasible due to safety constraints, ground conditions, site geometry, and overhead services.

Community and stakeholders

  • Have schools and bus services been consulted?

Yes. The project team has engaged with schools and bus operators to coordinate arrangements and minimise disruption.

  • How has community feedback influenced the project?

Feedback has resulted in a deferring the start date to reduce disruption and allow additional stakeholder engagement.
