More bus gates, one way traffic systems and rerouting of cycle lanes are being considered as part of a revised bus core corridor project in Dublin.
The National Transport Authority revealed that it received 13,000 submissions on the project which involves some compulsory purchase of front gardens and felling of trees to allow road widening.
It is designed to allow up to two bus lanes, two general traffic lanes and two cycle lanes on 16 key radial transport routes.
Of the submissions, 2,760 concerned the Rathfarnham to City Centre route while there were 1,231 concerning the Bray route and 767 about the Swords route.
Consultant engineer John Fleming told a meeting of the city council's Transport committee that revisions being considered include bus gates at Moibhi Road on the Ballymun Route, Stoneybatter on the Blanchardstown Route, at KCR and Harold Cross on the Kimmage Route and in Rathmines for the Rathfarnham route.
Bus priority traffic lights are being considered at Crumlin Road for the Greenhills Route and at Merrion Road for the UCD/Blackrock route.
One way systems are being considered for Rathgar Road for the Rathfarnham Route and Grattan Crescent for the Liffey Valley Route.
Alternative cycle routes are being considered to avoid Rathmines and Phibsboro where diverted cyclists could go under a bridge at Royal Canal Bank.
Mr Fleming said a new bridge for cyclists and pedestrians is being considered to span 'Hamburger Junction' where the Nangor Road, Naas Road and Long Mile Road meet and where it can take 9 phases of crossing for a pedestrian.
He added that the NTA was leaning towards a two-way system at Santry village with road widening and the transport authority may pay for recesses in raised gardens to compensate for the loss of on-street parking.
Works are planned to start in 2021 and continue on a phased basis until 2027.
