Maintenance Scheme

Part of our ongoing programme of work to maintain England's strategic road network

Cost:  Total Cost is £2,122,916

Managed by:   Area 7


Where was the project located?

Works were located over 30 miles (49km) of the A14 from the M1 junction 19 at Catthorpe and ending at A45 Thrapston junction (13).

Why was the scheme needed?

These works were required due to the existing filter drainage reaching the end of its serviceable life due to build-up of silt, soil and detritus.

What work was carried out?

The filter drain will be refurbished in localised sections on both the nearside verge and central reserve. The stone within existing filter drains was refurbished and recycled on site. This was done using a proprietary mechanical system. The existing stone was excavated and placed in the machinery which then removed the soil, silt and detritus. The recycled filter stone was then placed back into the filter drain trench.

How did this benefit road users?

The works have now reduced the risk of surface water flooding and ponding and increased road safety for all road users.
