Lanes 3 & 4 of 4 Closed Sign – WK 048 | Temporary Ireland Traffic Sign

Lanes 3 & 4 of 4 Closed Sign – WK 048 | Temporary Ireland Traffic Sign

The WK 048 – Lanes 3 & 4 of 4 Closed Sign is a critical temporary roadworks sign designed to indicate that lanes 3 and 4 (the two rightmost lanes) of a four-lane Level 3 road are closed ahead. It is essential for motorways and major dual carriageways where phased lane closures require a clear and early warning for drivers to begin merging.

This sign provides unambiguous direction to stay within the left two lanes, improving traffic flow and safety in high-speed environments. WK 048 is widely used in Chapter 8-compliant Temporary Traffic Management Plans (TTMPs) for major roadworks, resurfacing, barrier upgrades, or emergency closures on multi-lane carriageways.
