Security has been tightened throughout the country with police and military seen patrolling key urban areas in anticipation of expected anti-government protests scheduled for independence day.
Midday arrived without any sign of the planned demonstrations.
People living in Dar es Salaam, Arusha, Mbeya, Mwanza reported an unusually slow start to the day, with many people choosing to remain indoors amid uncertainty over if the demonstrations would proceed.
The protests were organized to demand changes to the political system following the unrest that followed last October's elections which resulted in an unconfirmed death toll.
Officials have conceded using force against protesters, claiming that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday nearly empty streets in the business hub, Dar es Salaam. This was a stark contrast to the city's usual weekday bustle.
The quiet was undercut by a persistent sense of tension.
Armored vehicles were spotted cruising along primary thoroughfares and junctions, while officers took up positions at strategic locations, particularly near important public buildings and facilities.
On social media, activists and campaigners urged supporters to stay alert, suggesting any demonstrations were unlikely to begin until the afternoon. The messaging echoed previous protest calls in Tanzania, when turnout increased later in the day.
Drivers who went out experienced frequent checks at roadblocks, where police interrogated motorists about their destinations.
The government has not issued detailed comments on the increased security or on the scheduled demonstrations.
Tanzanian authorities have banned the planned protests and cancelled independence day celebrations, urging citizens to stay indoors.
"An eerie quiet masks the underlying tension felt by those indoors."
The day's events painted a picture of a country under strain, where the threat of protest led to a preemptive security lockdown that left conspicuously quiet typically busy cities.
