Here's what you need to know to start your week in Central Austin:

1. Uber and Lyft are back

Gov. Greg Abbott paved the way for ride-hailing giants Uber and Lyft to return to Austin this Memorial Day weekend after signing off on House Bill 100, which does away with local regulations, establishing statewide regulations instead. In Austin, that means fingerprinting is no longer necessary for drivers working for ride-hailing companies.

2. City offices closed

Austin municipal offices are closed today in observance of Memorial Day. Capital Metro is running on a Sunday schedule, and Austin ISD offices are closed.

3. 2018 potential city bond amount grows

Weeks before Austin City Council is set to hear project proposals for the 2018 bond, a city of Austin staffer tells Community Impact Newspaper the bond capacity has more than doubled from its original estimates. This does not imply the city will have $500 million to spend for next year, but rather that is how much the city will be able to spend without impacting taxes over the next eight years, which is the life of a bond cycle in Austin.

4. Busiest summer ever expected at airport

The Austin-Bergstrom International Airport predicts this summer will be its busiest yet. Currently, passenger traffic is up 6.5 percent over 2016, according to a news release. Last June, the airport served 1,135,796 people, aviation activity reports show. The predicted increase comes as six new nonstop flights are set to launch between June and August.
