The M4 cyclic closures between junctions 1 and 3 are carried out every
six weeks, with the eastbound carriageway closed the first Monday-Thursday
and the westbound the following week. Full closures are required on the
grounds of safety because it is not safe for the workforce to be working
on the elevated section with one lane open. The width of the carriageway
does not permit sufficient safety zones for most of the works carried
out.
With regard
to the work undertaken, it is more extensive than may appear obvious.
Work includes the following:
- Sweeping
of the hard shoulder/verge and the central reserve
- Litter
picking
- Gully
cleaning
- Lighting
repairs
- Communications
systems repairs (this includes the roadside telephones, cctv cameras,
gantries etc.)
- Barrier
repairs and repairs to all other damage resulting from accidents
- Survey
of the structural joints and subsequent repairs as required
- Structural
surveys
- Carriageway
repairs
- Sign cleaning
- Re-lining
of the lane markings etc.
Every effort
is made to reduce the disruption to the travelling public. Advance warning
signs are displayed two weeks prior to each cycle of closures. Signing
on the night of the closures divert traffic along the A4. Work is completed
as soon as practicable and whenever possible closures later in the week
are cancelled.
