sentences:  This road has become somewhat controversial due to the relatively high toll charge and the closure of surrounding roads designed to funnel traffic through the tunnel.All Sydney tollways accept E-tags; the Westlink M7, Sydney Harbour Tunnel, Cross City Tunnel, Lane Cove Tunnel and from 1 December 2007 on the M2 Motorway have no cash booths, just E-Tag readers to zoom on through as they charge their tolls only through electronic tolling methods or through the use of number plate reading as you go through, then you have to pay after a certain time frame (for example; before 24 hours), otherwise you will get a fine in the mail.The M5 Motorway moved to electronic only tolling in 2013.
