It will be a few more weeks before repairs to the St. Charles Avenue streetcar line’s track are finished, officials told the Regional Transit Authority board Tuesday.

The track has been under construction since 2011, and crews were expected to wrap up the work last week.

But frequent heavy afternoon rains have stalled the last parts of the project, preventing trucks from getting onto the neutral ground and causing delays for other work, said Brendan Matthews, who is in charge of maintenance for Veolia, the company that runs the day-to-day operations of the RTA.

Those delays mean the work will continue for another two weeks, Matthews said.

The project, estimated to cost about $7 million, has faced setbacks from its earliest days, when the contractor walked away from the job and left construction in a state of limbo for months. What was expected to be a yearlong project then stretched out over more than two years as other construction delays set in and officials had to divvy the work up into smaller phases.

While the work has been underway, the RTA has used buses to shuttle riders along parts of the St. Charles route where the tracks are torn up.
