DETROIT, MI - Dan Gilbert has a vise grip on downtown Detroit real estate, and he may soon have a hand on the internet connections downtown, too.

Dan Gilbert, founder of Quicken Loans and Rock Ventures, confirmed via Twitter Saturday night that he's brining a newly-formed high-speed internet service provider to downtown Detroit.

And, as Gilbert said on Twitter, the service will be fast -- up to 100 times faster than what's currently offered in Detroit.

Rocket Fiber LLC was formed in 2014. Gilbert called the company a "community investment initiative", according to the Detroit Free Press.

The first wave of installations will happen in the downtown area between the Lodge on the west, I-375 to the east and I-75 to the north. After that, Gilbert will expand along Woodward and into Midtown.

Crain's Detroit Business reports that construction is already happening on the "advanced fiber-optic network" downtown. The internet service provider will operate on "hard-wired fiber-optic lines that well be connected to buildings."

Those using the service will use either ethernet cables or Wi-Fi to connect.

Gilbert said on Twitter that more information would be available over the next few weeks.

Currently, Gilbert owns 70 properties totaling 10 million square feet in downtown Detroit. He's invested, to date, over $1.6 billion in Detroit.

According to public information, here's a chunk of what Gilbert currently owns downtown. Place your cursor over the map to see his properties:
