Short lengths of unsealed road sandwiched between sealed section causes maintenance issues. This section of road is narrow with overhanging trees located close to the road. There is a causeway which has very poor vertical and horizontal alignment on the approaches.It is proposed to widen this section of road to achieve a 7.5m seal. Works would involve tree clearance / trimming, extending stormwater culverts, pavement rehabilitation and seal. Installing low flow box culverts under the causeway will allow a small realignment to improve the poor approaches.
