All routes will loop clockwise around the Custom House there will be a bus stop to the south of Busaras where passengers will be picked up and this will allow integration with Luas, Heavy Rail and provincial bus services. The route turns onto Amiens Street before making an almost immediate right onto George’s Dock. Minor changes will be required to road markings and traffic signals to facilitate this turn.
George’s Dock is open to two way traffic and no changes are required.
At the junction of Mayor Street Lower the road becomes three lanes with two Luas rails and one Eastbound lane open to all traffic. The road is sufficiently wide to allow Westbound traffic with a constraint at the Luas stop outside the National College of Ireland. Which may need guided bus kerbing or alternatively require Westbound traffic to yield to Eastbound Luas trams.
The three lanes continue through the Guild Street junction and over the canal. Just before the junction with Park Lane Westbound land in restricted by bollards, however, the road surface is still present. After the junction the Spencer Dock Luas stop constrains the path to two lanes which may require guided bus kerbing or alternatively one direction of traffic to yield to the other.
The route continues along Mayor Street Upper as two lanes of shared road space until the Point Luas stop is reached. This is a wide plaza and there are several options how the route can traverse this section where the right of way of Castleforbes Road has been preserved. The BRT route will have no stops along the Docklands Luas line and a stop at the 3 Arena may be facilitated if required away from the Luas stop.
The route will turn left onto East Wall Road which will require new traffic signals to prioritise the BRT route. Additional bus prioritisation measures will be required along East Wall Road on both sides which may lend itself to an equivalent of the Red Route prioritisation measures that have been adopted in the UK.
The route proceeds through the Port Tunnel bypassing the toll booths.
At the airport junction with the M50 airport traffic exits proceeds through the roundabout, which will require prioritisation and then serves Terminal 2 and Terminal 1 before returning via the same route. At the roundabout over the M50 the elimination of the traffic signals and the removal of the ability to U-turn onto the Northbound M50 will facilitate the prioritisation and minimum cost.
For routes destined for Swords the route continues to the Airside junction through Holywell on the existing road. A new bus lane may be required along both directions. Traffic destined for Rivervalley turns left at the roundabout and proceeds through the junction with the R132 to serve Boroimhe and two stops in Rivervalley before returning in a loop via Forest Road and proceeding back to the city centre via the same route.
The second Swords route continues straight at the Airside roundabout before turning right at the Pinnockhill roundabout where there will be a stop. This section can be congested so prioritisation measures will be required on this section. The route continues along the Swords bypass stopping at the Pavillions, Seatown Road, Balheary Road before proceeding to the Lissenhall junction with the M1. Lissenhall has been flagged as a Park and Ride location for the Metro North project and this may potentially be used to facilitate this facility at an earlier time. The route returns to the city centre via the M1.
