Taxiing in last night; we were cleared in to the gate from the Southport on the Bravo line. It was snowing; but 34 degrees; so just wet; no snow sticking to the surface. Once we crossed the Alpha taxiway into the Southport; it was impossible to see the Bravo line. Neither my FO nor I could see the yellow taxi line. I stopped the taxi while we navigated where the line was and a de-ice truck drove by on our right hand side.  These taxi lines need to be repainted. This is a huge safety hazard as it could cause an aircraft accident.
Air carrier Captain reported ORD taxiway Bravo line should be repainted.
