Long awaited road works to upgrade a notorious junction in Blanchardstown are due to get under way shortly.

Fingal County Council has begun the tendering process to appoint a contractor for the Snugborough Interchange Upgrade scheme.

The project will involve building a new bridge over the N3 with bus priority lanes and other measures to alleviate traffic gridlock at the intersection.

A new footpath and cycle track are also planned as well as a new pedestrian and cyclist underpass to make the junction safer for users.

Local public representatives have repeatedly called for the road upgrade as a matter of urgency as the bridge is a black spot for traffic gridlock at peak times, with motorists waiting for up to 30 minutes to get through the lights.

Cllr Tania Doyle (Ind) said: “As a frequent traveller through this famous intersection myself, I am delighted to see this project advance.

“While the project will improve traffic flows at this junction, a key benefit of the upgrade will be the significant improvements for public transport users.

“I look forward to seeing this scheme moving onto the construction phase, which will hopefully get under way next year.”

Measures to improve traffic flow at the two junctions will include “bus priority measures” that support Bus Connects objectives.

A contractor is expected to be appointed by December and the scheme is expected to take 24 months, with diversions on the N3 and Snugborough Road.

FCC senior engineer Paul Carroll said: “A key benefit of the upgrade will be the significant improvements for public transport users, pedestrians and cyclists on the bridge and at the adjacent junctions.

“This scheme will strengthen the connections between Blanchardstown Village and the Blanchardstown Town Centre and residential areas to the N3’s east.”

The project is financed by Fingal County Council and the National Transport Authority.
