The busy Sefton Lane/Liverpool Road South junction currently has no pedestrian crossing facilities. But people of Maghull are calling for a new pedestrian crossing to be installed.
The estimated cost of the crossing is £40,000.
Cllr Carr says that is money which Lib Dem-run Maghull Town Council should find.
He said: "A pedestrian crossing is long over due at the junction between Sefton Lane and Liverpool Road South. People have been calling for this for a long time - but there is obviously a cost implication.
"The Lib Dems are asking the Primary Care Trust to pay for a new pedestrian crossing at the junction. But this will inevitably come out of other health funding which will affect patient services. With the cuts which the Conservative-Lib Dem coalition government are introducing, then this is funding which the PCTs simply cannot afford."
The Molyneux councillor says the town council are responsible for finding funding.
He said: "Maghull Town Council have a duty of care to the people they are supposed to represent. They should be supplementing Sefton Council's budgetary constraints which have been brought on by this Conservative-Lib Dem coalition government.
"I want Maghull Town Council to look for funding to go towards the cost of the pedestrian crossing.
"Maghull Town Council are looking to buy solar panels for the town hall which reduce costs in 10 years' time.
"Surely the council can look for funding for this crossing which will make life easier right now for people in Maghull and will end up saving people's lives.
"It is essential that a pedestrian crossing is installed at this junction. Bare in mind that many pedestrians using the junction are making their way to the nearby doctor's surgery. It's difficult enough for an able-bodied person to cross - it is very near impossible for a person with an ailment or disability.
"Let's not wait until someone is killed before action is taken."
